Agree on the wood - very nice.
I must admit that I don't know when the "Lee Speed" patent stamps ran their course or, exactly, what those patents actually covered.
Maybe your's for all purposes is a Lee Speed just not marked so.
The front sight on your rifle looks awfully Webley like to me the way it's shaped and sleeved onto the barrel. I've seen very much the same sight on some bigger bore single shots some with the grooves for the hood and some without.
