Old Rifle - what and any idea of value?

[pee wee]

Have a buddy come across this. He says from revolutionary war period he was told. Most of the action is there, doesn't operate. He wanted to know if I had any idea what he had. I believe he's got an opportunity to acquire, if not for just a wall hanger.

What say ye?

Definitely not an expert, but the stock style in picture #3 looks like it’s a Turkish style
