I have a Webley Mk VI that I purchased some time ago. What's nice about it is that it's still chambered for .455 Webley. Most Webleys that you find in the States have had their cylinders shaved so they can fire .45 ACP. The big bore Webleys are arguably the finest combat revolvers in military history.
I'm still on the lookout for a Webley Mk IV in .38 S&W.
