I have a good friend who is looking to move on his very extensive collection of under lever carbine rifles. Can anyone suggest who I would be best to talk to regarding this? Are there any specialists out there with a particular interest in this kind of thing? They're mostly in pistol calibres but there's a .303 or two as well, there also appear to be a few originals in the collection rather than just modern replicas. Everything is in excellent condition. Any pointers in the right direction would be gratefully received.
