As you can see the body is covered with a green/brown volcanite, a color that looks like some of a 1935 Fed. I have another Zorki 1b export, N°32025, lens N°35300, but it is a normal dark gray.
Are there other Zorki with the same volcanite color? I have anothert one, but is a Zorki 1c and it is strange some other ways, but i leave this to another post.
