I have accidentally found this camera on eBay. It seems to be a new masterpiece of our friend "moscowphoto" (cameras "USSRPhoto 5 y.a.").
I have never seen any information, that this camera was ever produced. This camera is definitely home-made replica and I didn't understand, why the seller marked it as "Extremely rare item". Any other ideas?
I think he says it is extremely rare because there is no production for this camera.. It is only a home and hand made product, and only in very very small quantities... I got one some years ago...
It is the Leica 75 which is extremely rare!... (in fact, it was only made as a prototype).
As for this Zorki 75, I agree with Fred: it was never officially produced. Certainly it's a pity: it's a beautiful camera and KMZ could have done it easily. Moscowphoto should be more clear in their explanations...
