Abrahamsson Rapidwinder – Classic and M2-IXMOO


 Rapidwinder Classic and  M2 Rapidwinder IXMOO 

Rapidwinder Classic  fits  M4-2, M4-P, M6, M6TTL, M7, MP and MP-3 without modification to the camera.  M3 and M4  and MDa can be modified to take it.

M2 Rapidwnder-IXMOO fits the M2 and MD without modification.

A limited edition 94 of M2 Rapidwinder-IXMOO were made. With this  Rapidwinder-version you can use the reloadable Leica IXMOO-cassettes or regular film. 

The “BarnackWinder”,  Rapidwinder for Screwmount Leica IIIc/g/f was  in production during 2003 -2013.  A limited edition of 25  were made and sold.

Tom’s story about the birth of the Abrahamsson Rapidwinder Classic which has been in production since 1987

The original idea for the Rapidwinder came about after the demise of my Leicavit MP’s. They were impossible to repair and had become prized collectibles and furthermore they did not fit the M4-P’s and M6’s that I was using.

In 1987, I proceeded to make a small batch of brass housings and drives that would engage the drive connection for the Leica Power-winder and after several trials and errors I managed to get some working prototypes going.

In 1989, I realized that modern technology allowed me to have the cases machined from alloy, using Computer Numerically Controlled (CNC) milling equipment. 

Today the  Rapidwinder Classic is essentially the same machine as the 1989 version, although I have kept on upgrading parts and designs as time has gone by.

Specifications of the Rapidwinder Classic and the M2 Rapidwinder-IXMOO

The Rapidwinder adds 14 mm to the height of the camera and 125 grams to the weight, the multiple pin clutch used in the drive allows the user to shoot very fast. It is possible to achieve up to 2-2,5 frames/second with experience.

The material used in the Rapidwinders is high tensile strength alloy, stainless steel and brass. The drive is a reinforced toothed belt, quieter than the original chain drive of the MP’s as well as less prone to stretching.

The original Leicavit MP was a very complex design, containing 50+ parts in the housing. The Rapidwinder  contains less than 10 individual parts and can, in most cases, be serviced by the user.

The finish of the Rapidwinder cases is matte and brushed “chrome” alloy for the M6 winders and a brushed “chrome” anodized finish for the M2 version.

The Rapidwinder is particularly convenient for those of us who focus with our left eye. For years we had to deal with film advance levers poking us in the right eye or having to drop the camera slightly to advance film, thus breaking the concentration when shooting. 

User Testimonials

“Tom’s Rapidwinder is as quiet as if you advanced using the thumb of your right hand in the normal fashion. Quite frankly it is silent, fast and of efficient action in the use of the camera. For any M6 camera user it’s wonderful. However it’s a God sent gift for those of us who are left eyed shooters.” Dr.Ted Grant, Victoria, BC, Canada

Thank God Tom Abrahamsson is left-eyed. Left-eyed Leica photographers are always sticking their thumbs in their eyes when they use the thumbwinds on their cameras. It’s not a problem for right-eyed photographers or even left-eyed users of motorized SLRs. Indeed, my EOSs don’t even have thumb winds. But that small, quiet camera, the Leica, that sees so well in dim light, has a thumb wind. And I am left-eyed. And I am tired of taking the camera from my eye to wind my film. Or sticking my thumb in my eye when I forget. Tom has solved the problem. He has made a rapid-trigger basewinder, in essence an improved version of the old Leicavit basewinder made in the early sixties for the Leica M2. Worked by the left hand fingers that are not focusing the lens, the basewinder can advance the film at a rate of 2 to 2 1/2 frames per second. Yes, faster than a speeding thumb. The best I can do with a thumb wind is about 1 1/2 frames per second. Far more important, I do not have to displace my camera from my eye and lose my concentration on the subject in order to advance the film.

Certainly, for anyone, left or right-eyed, using the center-mounted auxillary finders with the 21, 28 or 90mm lenses, winding without pulling your eye from the viewfinder is easier and faster with the RapidWinder. That can’t be a full explanation for the popularity of the winder with you right-eyed people. The best I can fathom from my right-eyed bretheren is that the winder adds a “near-motor experience” without the additional weight, size, noise or dependance upon batteries of a conventional motor. Oh, and you also get a centered tripod socket in addition to the normal Leitz socket, and a lot of weird looks from Leica collectors. And, most important, since those collectors have scoffed up all the old M2s and Leicavits, the RapidWinder fits on the current M6 and the M4-2/M4-P. Tom also makes a version for the M2.

Here are the specifications of the winder as copied from Tom’s website: “The current version fits the M6, the M4-P and the M4-2 without modification to the camera. It adds 14mm to the height of the camera and 125 grams to the weight, the multiple pin clutch used in the drive allows the user to shoot very fast.

It is possible to achieve up to 2-2, 5 frames/second with experience. The material used in the RapidWinder is high-tensile-strength alloy, stainless steel, and brass. The drive is a reinforced toothed belt, quieter than the original chain drive of the MPs as well as less prone to stretching. The original Leicavit MP was a very complex design, containing 50+ parts in the housing. The RapidWinder, on the other hand, contains less than 10 individual parts and can, in most cases, be serviced by the user.”

Tom travels a lot–Germany, China, Japan, Cuba, and even Boston in the last few months. But you can drop by his website anytime at http://www.RapidWinder.com. You get to see a few more things a photographer who is a good machinist can come up with. My favorite is a “goggled” 21mm lens. Tom designed it and a famous Leica repairperson executed it. With the 21 on a rangefinder camera, you normally use an auxiliary finder. Leitz once made a “goggled” 35, it had an optical attachment which expanded the 50mm frame of the M3 to one for a 35. They added those goggles to a 21mm lens and produce a lens that needs no auxiliary finder on a current Leica. Sounds very useful, but it does pose the question, “What did they do with all the 35mm lenses that were originally attached to the goggles?”

Leica M RapidWinder Genealogy by Stephen Gandy of Cameraquest

Stephen Gandy’s Cameraquest, California

The UR RapidWinder begot the 9 Prototypes, and the 9 Prototypes begot the production RapidWinders, and Tom saw that it was good..

Tom Abrahamsson’s background includes stints as a professional photojournalist and a  professional industrial designer.  His Leica   M RapidWinder  is a marriage of his professions … if you leave out extraneous jobs such as Ferrari GTO car trader and King Cobra transporter (the snake, not the car).   The production of the UR RapidWinder was no easy task, because Tom had absolutely no experience as a machinist.  He started from ground zero.  Standard RapidWinders fit the M4-2, M4-P, M6, and M6 TTL, but M2 RapidWinders have also been produced.  All RapidWinder pics on this page courtesy of Vancouver’s famous Tulikki Museum of Industrial Design.

RapidWinder Dates

  • 1984  idea for UR RapidWinder, without any belief they would be produced commercially

  • 1987 1st UR RapidWinder, followed by P02 to P09 Prototypes

  • 1987-1989  164 production brass shell RapidWinders produced, numbered A001 to A164

  • 1989 new milled one piece aerospace winder body introduced,  individual RapidWinder numbering discontinued

  • 1988  Chain inner drive replaced by more reliable rubber drive

  • 1996  mild steel trigger replaced by stainless steel trigger

  • 2005 Limited production of 300 M2 RapidWinder introduced

  • 2000  RapidWinder with Grip added to production lineup

  • Older RapidWinders sent in for maintenance are often upgraded with later features, so it is not unusual to find a RapidWinder with a mixture of different features

UR RapidWinder

RWGen2.jpg (872308 bytes)

This is IT, the legendary UR RapidWinder!    Tom 1st got the idea in about 1984, but this first  hand made brass M6 UR RapidWinder prototype was not produced until 1987.  Notice the Leica M type opening key, which was dispensed with in later versions as being too complicated and time consuming for practical production. Notice the lever wind lock is also different from production RapidWinders.

Prototype Number 7

Eight  prototypes were produced, numbered P02 to P09.   This is the M2 “Mickey Mantle” Prototype, good ‘ol Number 7.

Compared to the UR RapidWinder, notice the differences in the RapidWinder lever, its lock, and the closing latch, as wall as the addition of the engravings.

Prototype Number 10

 RWGen16.jpg (737645 bytes)

This is the last prototype, P-10 for the M2.

1st Production RapidWinder

This is the 1st  production RapidWinders, number A-001.  The outer shell and bottom are built from two pieces of brass.   This construction was continued until number A164, when it was replaced with a one piece milled body.

RapidWinder Variations

To date about 3,000 RapidWinders have been produced in total,  a very small figure compared to all of the Leica M bodies.   So, they are comparatively rare.  Are the variations collectible ?  You decide.  The standard RapidWinder finishes are black matt and black glossy, but many more finishes and variations have been produced, enough to present a very challenging task to the devoted RapidWinder collector:

  • M6 “Titanium” finish for Titanium M6.  Actually, these are nickel plated,  but the nickel provides a great match for the M6 Titanium bodies.    Production approximately 30
  • M6 Hard Anodized Brass,  20 were made by special order for a Japanese camera dealer
  • M6 Blue Anodized, one
  • M6 Black Glossy LHSA, two for LHSA M6 TTL
  • M6 24k Gold, one
  • M6 Purple/Turquoise, one for the Jerry Garcia Purple Haze Commemorative
  • M6 Red, three
  • M6 Green, three
  • M6 Gold paint, three
  • M2 RapidWinders, about 260 to date.  Most are silver finish, but 40 are black, and a few  special order colors
  • M2 Grey Hammertone,  one
  • M2 Blue/Grey Enamel, one — proudly residing in Stephen Gandy’s camera bag on a matching Shintaro painted blue/grey M2.  Oddly enough, Tom found it “too pretty to use.”

Stainless Steel Drives

Very rare Super Deluxe RapidWinders have stainless steel drives.  The stainless steel makes for even a smoother advance.   These have never been listed for sale, and very few people even know they exist.  While the standard RapidWinder drive mechanism takes about one hour for Tom to machine out of brass,   the same drive out of stainless steel takes about six hours for Tom to produce — not an easy task.    Six were made on special order for National Geographic.  The other two dozen or so were not sold, they were bartered.  Tom refuses to sell them, and only trades them for prints by photographers he both admires and respects.
