Thank you all for the suggestions. Sorry to be late in replying to the posts. Doing the Christmas celebration with the family. I will take another look at the lock in the morning. The screws were not all that tight, and the rifle function for a long time very well. It seems the sear had some ware on it, so perhaps a very fine stone and elbow grease will work. I will double check the wood, to make sure nothing has changed. These are a nice M/L and very accurate with a .490 ball and 70 grains of FF.
Now on to the next project a H&R Trapdoor Springfield newly acquired.
Best Regards
Paul
