HURRAY! I finally found a way to post photos here!
I have had this lock for quite a while and don't recall where I got it. For the longest time I thought this was a Dutch lock but the more I learn, it seems like it could be an American made piece. Lately I have been able to get my hands on some fine Bedford County locks to make molds from and I do find similarities. I have castings for one cock that would fit and look OK. If there are any Bedford/Somerset County rifle gurus out there, I would appreciate any input. What do you think?
