From OLD CAMERAS (Starie Fotoapparaty) two more photos
4 Apr at 10:00 pm•from Alexander Tkachenko
I came across such a device. This is clearly Zorki-5 of the first issue, but the inscription is a little confusing. What is this, homemade or were there some limited editions with that name? No information could be found; with the name Rubin there was only some kind of copying machine (according to other sources, a KGB camera) and an observatory. Although, a certain Rubin-Zorkiy is mentioned on the resource exponat-online.ru, but there is a photograph only upon request, and it is not a fact that it will be sent.
