Two USSR camera & equipment bags, both real leather. The big "professional use" bag was also made in leatherette, almost paperlike surface, and was propably not rare as I have seen several. Otherwise big cases like these we not common in USSR.
The smaller one was also made in some kind of Vinyl, brown in color. It was very unreliable, and the zipper was guaranteed to fail quickly.
The large, black leather bag (also called "kofr") was of excellent quality, with suede lining and some compartments inside. It was also very heavy.
