One thing that's useful about later versions of FSU cameras is the terrible rubberized fabric covering that was used on them. Useful, that is, because it's easy to get rid of and thereby improve the camera. And it's not as if you are desecrating a great collector's item by doing so.
I recently bought a Zorki 6, which turned out to be a surprisingly nice camera. While it may not might challenge the FED-2 for the title of prettiest FSU camera, it's not bad at all, and the winder and viewfinder are really quite good. But the fabric covering doesn't do anything for it at all.
So I went to Tandy Leather, and got some thin brown pigskin leather and had at it. I could have gone wild with ostrich skin and the like, but wimped out, as the leather could end up being more expensive than the camera. It took about an hour to complete. Here's a before and after.
