Thank you all for commenting on the piece. I had also noticed the 'feathered/eyed' hammer found on many percussion pieces of the period. I am leery on taking the gun apart to look at the lock from the inside. As the pics show, there are some instabilities/cracks in the wood. The piece is solid and intact, but once one starts unscrewing the mounts, I'd be afraid I could ruin the piece. I might just have to chalk this one up as a 'possible' conversion. As I am not an expert, I don't want to cause any more harm to it-
