A spring in a very old lock (perhaps 150 years old) has broken. I managed to dis-assemble the lock, and found the broken spring - a flat U-shaped spring with arms about 6cm long. I'm wondering how I can get a replacement for this? Is it by chance a standard piece? the spring turns around a splindle.
The lock is in a very large partition door (about 12ft tall). The actual lock is not used - just the catch, to keep the door closed.
Any suggestions gratefully received.
