Hence the Many Klatch ?. I have not named what I thought the' poor' locks Some fine locks where made by Mack Vance, Pete Allan, & Larry Zornes besides North Star .Caywood & probably many other good locks even the ubiqueus 'Lott' And Dixie Ketland would' work up' I remember buying the Ketlands 'three for a bill' .But once you sorted the springs balance they where fine locks'. I had four styles of flint lock various percussion and even Wheel locks made in India . They varied but all I used got up fine and are still giving good service & non had ' off the shelf' spare parts . I once asked" What steel do they use ? " They replied " We are makeing with the help of the e'scrap ". Generally we are today blessed with many locks to choose from and the exotic wish list offering of parts from Rifle Shoppe & Ted Blackley are mind boggling ( boggles mine anyway !') . There you are i'me about' Locked out ' . Well better than being locked up ! .Russ Hamm made locks. He may have made good ones but that wasn't what I got. There was no way to harden the frizzen so that it would spark.
