Not possible. I've only a few Zorki.
🙂
I have perhaps about 12 or 15 Zorki-1 specimens belonging to the "Ib" series. Of these, only 2 (one has the same pigskin covering described in the website quoted above) have really soft bodies. One has an indentation which would give an impression that it was distorted by a thumb (the opposing thumb will land on that area when the camera is grasped), but careful examination would "finger" the culprit as the ERC snap.
The other 'soft' body Zorki (dual Zorki-Зоркий engraving, round pressure plate) doesn't seem as soft though as the one previously described. It will not bend with normal handling and it would take a lot of effort to even start putting a hand-made dent on it. This Zorki body has the same density as my 1935 FED-1's shell. This FED had a distorted body when I got it, but was reformed by using a wooden form and some beating:
The rest of the Ib types I have have bodies which are as robust as the later Zorki-1 with non-diecast bodies. They match contemporary FED-1 in this respect. These Zorki have serial numbers of 115xxx or 117xxx or higher. Many of these are definitely not "1c" or later, since they all have the same external features of a typical 1c (no "stripes"), and someof these no longer have the round pressure plate.
The tight film chambers are also found only on the low-numbered bodies. The crates in these cameras, still the stamped, multi-piece FED-derived type, has indentations on the side facing the film chamber. Its indentation coincides with the area between the caps of the cassette. This in effect 'hugs' the cassette rather tightly and causes the sharp, crimped caps to catch on the indentations, making the cassette hard to retrieve. The same has been observed in some late FED 1g (SN above 65X XXX). In either camera, this problem can be eased by some filing on the crate. The part of the body shell which forms the film chamber can also be beaten to shape a bit to make space for the cassette.
