when I am done shooting, I lube with remoil, or a silicon based lube.

here's what I found, sear has a hair like crack in the eyelet, grooves cut into the plate by moving parts. (sear and tumbler) pitting on the plate (where there when I bought the darn lock.

I had a plan to revive the lock and mod it for a project. just too much wrong with it. should be able to use a few parts for back up for my 50cal.
wear marks shows up well where the sear is.
