I've been giving my new FED-2 a full service and overhaul, and I have it in seemingly good shape now, however, the rangefinder lens itself (the small lens mounted on the body for adjusting vertical positioning) has been hopelessly mangled by a previous owner.

This unfortunately means that I can't rotate the inner barrel (with the glass mounted in it) as the inner and outer barrels have become fused.
If anyone has a spare rangefinder lens lying around, I greatly appreciate it if you could pass it on to me so I can get this camera back up to fighting strength (I can offer money for the part). I am in the UK.
