Hello,
I have just received an interesting camera. It is a Fed 1a converted to a Leica.

The engraving is bad. As it was made on a "machined" top (galvanised), it is not regular and one can see the brass. And "DRP" on the top and Leitz on the lens are missing...

The serial number is 5431. There is no difference with my regular Fed 1a # 5330, except the engravings and the silver rims, rather than brass ones on the rangefinder/viewfinder. The lens is a Fed "1 turn" reingraved...
Of course, I am very happy to get this camera. But sad too to see such a rare camera converted into another one. Anyway, it would be interesting to know when that was made. Inside, near the rewind button, there are some cyrillic letters (difficult to read) with something which could be a date : 8/41...
Amitiés. Jacques.
