My husband brought home a $10 garage sale box of photographic oddments. In the bottom were some small lenses in little brown leather cases. Ignored them for awhile, then wondered if they'd fit the Yashica LM. Proxars! Awesome! I've uploaded some photos to the gallery from my test roll. There's also yellow and red filters the right size, but they aren't threaded. It appears there must have been a ring of some sort that would have been used to attach them. Can anyone shed any light on filters for TLRs circa mid-fifties?
