Hello all. Well, here's an update. He has removed the lock from the gun. The mainspring is too close to the lockplate to make out the rest of the name. So, he is going going to a qualified antique arms gunsmith to have the lock dis-assembled so we can read the rest of the name, and a "minor" cleaning of the inside. (I told him he didn't have to go to all that trouble. Just box the whole gun up and send it to me.

Oh, well. Meantime, here are some more photos of the lock. I'll report back in a couple more weeks. Thanks, Rick.
By the way, go to my other new Post and look at the cool battle axe.
