Just had a look on the shelf:
Zeiss Contax 50mm f1.4 - in it's day was said to out-perform any Leitz 50mm lens, but, my own tests show that the Fujinon XF 35mm f1.4 out resolves it when mounted on a Fuji X camera (but the Fuji does do software lens correction for Fuji lenses, so this may not be fair)
Zeiss Contax 135mm f2.8 - lovely bokeh, but it's quite heavy.
Helios 58mm f2 - this is one that I built from two I bought, so I ended up with good optics from one lens, and working mechanics from another - this was the lens on my first SLR - a Zenit B - it's really not too bad at all, characterful.
Yashica 200mm f4 - basically the classic Zeiss Sonnar design, built by Cosina in Japan, but to much less exacting standards than Zeiss. On my Fuji it's a 300mm lens, 35mm equivalent, but if I use my Fuji 90mm f2, and crop, the resolution is way better, and so it's unlikely to get much use.
I also have a Jupiter 9 - the 85mm f2 that has quite a following - mine is a 39mm (Leica) screw thread, and my adapter is a pain, as I need to shim the lens to get a proper infinity focus, and the lens doesn't then line up with the camera, so I can't see the aperture markings. At f2 it's really spectacularly poor, but stopped down it has an amazing quality to it that renders skin really well, so I'll be keeping it after all...
