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 besides the engraving on the top plate for the year. 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
