Jim, just an idea. You make left and rigth gunmakers flintlocks. Based on the siler pan, hammer and frizzen, it should be possible to make versions of these parts that would fit this lock. This make it easier to make different styles of locks based on the gun makerlock
You could cast a siler frizzen without the big noch in the front, and make a rounded pan.
This would make it a more an english style.
Best regards
