The RBL, of course!

Thorny, look back at the original post. You won't buy a new A&N these days, so that puts them out of the running. Back when they were selling guns (they never actually made any), however, you could get some pretty nice stuff from them--for less than a comparable Purdey or Boss would have cost you. Of course Purdey and Boss made best guns only, whereas the vast majority of the guns A&N sold were the much more utilitarian boxlocks.

I've been to the H&H works, and they certainly use some pretty sophisticated machinery--but a lot of the work is still done by hand.
