I think Larry had a mix up, it may be LC built the lock for Jim . It was a std Delux Siler . I did the tune up, polish job and the bearings .The little bearings are tuff as nails , the balls are stainless as is the whole bearing . The first one i did is over 4 years old and has had thousands of shots . Jerry i have one full ball bearing, spring toe, frizzen toe ane even frizzen piviot screw. I had to stop at the tumbler for other peoples stuff, i don't have the time to do the full bearing models. There are several out there , but i can't do many more than i can now. It is more or less good friends out there now that have them . I do have to say on the tune up LC Rice did teach me how to tune up a lock. I just took it a couple steps farther. Jerry if you want to see one ,Ron Scott has a couple out in your neck of the woods .I just want to add this! When you take a built lock and do what i do to them, you find out how good a job was done, when it was put together. I will only do this to Jim Chambers locks . The fit and finish is way beyond any other brand.
