Fixed a mangled and bent shutter blade on the Elgeet 38mm telephoto lens on my Bolex H8. The blades were so screwed (and I so inexperienced) that I had already written it off as trash, but a few hours of delicate tinkering led to a fully working lens! There was a LOT of misplaced grease and I didn't quite get it all off the internal elements, but it's at least usable now.
