Broken Mortise Lock
Hello all. I have a 1940 house with old (I believe original?) glass door knobs and mortise locks. My bedroom lock broke (knob would spin but the latch wouldn’t retract) and taking it apart it looks like it’s the spring mechanism but not the spring itself. I think a little metal piece broke off (circled below - I’m able to pick it up with tweezers which I couldn’t do with the working lock I took out to compare). Anyone dealt with this before and have a fix besides buying a whole new lock mechanism?
