My Lee needed a lot of parts including the safety assy, got one from Numrich, it came as an Ishy safety, works but it did not look quite right on my Lithgow, ended up ordering another safety assy from Marstar, The threads on the one from Numrich were too tight, so I had to lap the threads to make the thing function, I used fine lapping paste about 600 grit. Now it's just a spare I guess. If there's anyone out there in need of an Ishy safety assembly, I've got one, Don't know exactly where it is though :lol:
