Some 900 to 1000 Fed-Zorki 1949 were made.
The first known is #04811, the last #05749.
The first known Zorki-1a is #05784.
There are no real differences between the '48 and the '49. Of course, the engraving on the top plate is different for the date. Most of the '49 have shutters to 1/500s and crisp paint instead of bright paint under the bottom plate (see picture 3). The last known with 1/1000s speed is #04903.
Most of them were combined with the coated Industar-22 (K340 by Princelle).
Pictured camera (Jacques M. collection):
Zorki #05159
Industar-22 #1363
