Thanks for the input Smallpatch and oldtravler61. What I have is a Lehigh stock that is pre inlet for L&R Lock and swamped barrel. Both lock and barrel came with stock. Final inletting of the Lock, barrel, trigger, buttplate and side plate and thimbles remain for the stock work. Since this stock is pre carved as a Lehigh style I will leave it that way.
I like the Lancaster style and would have preferred it but acquired this set because the price made it attractive to get back in the game.
