Flavio,
Most, if not all Leicameters were manufactured by Metrawatt, who only a few years ago became part of Gossen. The 1955 version was called Leicameter M and it was the first meter that was fully coupled with the shutter speed dial of the M3.
The second version, the Leicameter MC came out I believe in the late 1950's. It was more sensitive and used an internal baffle for the high-low range, instead of the external flap of the original Leicameter M.
The third version - Leicameter MR, switched to a CdS cell instead of the Selenium cell of the M and MC and again had increased sensitivity over the MC. As well, the measuring angle of the MR meter was the same as that of a 90mm lens so that by activating the 90mm preview frame of the camera, one could do a more or less selective measurement.
The MR meter had an on/off switch on its side, which became rather awkward with the introduction of the M4 with its rewind crank. Thus - a second version of the MR was introduced, with the switch relocated to the top plate of the meter.
As to the number of meters produced, I am afraid that those numbers will be difficult to find.
All the best,
Jan
