I recently bought this camera in Japan and a serial number on it is from 1971, the production numbers are absent for this year on http://www.zenitcamera.com/catalog/cameraproduction.html
It also has the KMZ logo on the back which I haven not seen on later BMs.. Is this a preseries camera or just an error on the web site?
Zoom, any thoughts?
Does anyone else have a 1971 BM?
Thanks,
Vlad
