Leica M Rapidwinder Genealogy - as seen & reported by Stephen Gandy in July 2001
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, M6 TTL, M7 and MP but M2 Rapidwinders are also being produced.
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 CNC-milled one aerospace winder body introduced, individual Rapidwinder numbering discontinued
??? Chain inner drive replaced by more reliable rubber drive
1996 mild steel trigger replaced by stainless steel trigger
??? Limited (300) production M2 Rapidwinder introduced
???? 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
M2 Rapidwinder-IXMOO limited edition of 100 introduced in Nov. 2005
UR Rapidwinder

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

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.

49th Production Rapidwinder

M2 Prototype Rapidwinder


Later M2 Prototype Rapidwinder with one piece milled aerospace alloy body, soft steel trigger
Prototype Rapidwinder Grip

Prototype M2 Rapidwinder Grip. Most M2 Rapidwinders are silver like this one, but without the grip.
Rapidwinder Variations
By July 2001 about 3,000 Rapidwinders were produced in total, a very small figure compared to all of the Leica M bodies. So, Rapidwinders 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:
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 took 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. How to spot a stainless steel drive Rapidwinder ? Ah, that is the secret.
