Same engravings as on the 1f first series.
Two differences:
- The release button has a "bowl" shape.
- The standard of speeds is changed:
1/25, 1/50, 1/100, 1/250, 1/500 and B
instead of
1/20, 1/30, 1/40, 1/60, 1/100, 1/200, 1/500 and Z.
This change was made in 1952, much earlier than KMZ.
KMZ did the same for the Zorki-1 in 1955.
Serial number range: #300.000 to 400.000 .
