Broken Main Spring - Where can I get another?

[TN shooter]

Sadly, my Losey #54 has a broken spring. I have no idea who the lock manufacturer is. Any help in locating a source for replacement would be greatly appreciated. The spring length is 3.46" approx.

looks to me like it's a Chambers Early Ketland. If so, you can get a replacement from TOW for $25.50. Or you can call the folks at Chambers and order one.

I believe Mgbruch is correct, also order a main spring vice to make the installation much easier.

You can follow the link below to the Track of the Wolf's catalog to print out the full-sized illustration of the lock to compare to your broken spring. Based on what you observe, order a replacement spring. You ought to be able to find a matching spring among the 50 locks they have cataloged.
