It should have a standard 1/32" bevel. None of the locks you buy are finished when you get them. Jim Chambers intends you to file them up and polish them. Some light honing of the sear and tumbler might also be necessary. I have gotten a number of locks where the fly was just a hair too long and needed to be honed down some. Also, All 18th century locks should have some engraving. Even the cheapest English trade locks, which is what generally ended up on American longrifles, had some kind of engraving on them even if it was just a couple of outlines. I have seen the crudest made English locks with a good amount of simple engraving. Just like today, it wasn't what was inside that mattered as long as it looked pretty on the outside.
