I have found this rare Zenit B Global. It is in very good condition, inside it looks as if it was never used.
The shutter was stuck, it won't run after releasing, but with a litte bit force I was able to let the first curtain run :-) Now it works smooth.
Unfortunately the lens is not the original one, a silver-black Helios with white digits would be the right one.
