ZENIT B
Zenit B bought (bare body) on eBay on august 2nd, 2007 for 12$ +18$ sending fees.
The Zenit B Is not the precursor of the Zenit E, it is a simplified version of it. The lightmeter is no more there, ant it's calculator knob is replaced by a big rewind knob (which turns while the film advances). The rest is identical.
At left the lightmeter of Zenit E, at right the knob which takes it's place on Zenit B, with a reminder for the film speed or for it's type.
