Neat!
I would love to have a .455 Webley, but it's difficult to find one in original condition. I looked at a modified one as late as yesterday, but it's just not the same.
However, I did find a very nice Enfield No 2 Mk 1 a while back, it's not as cool as the Webley but it will at least keep my need for a British revolver satisfied for now. You just gotta love these guns, they are about as elegant as farm implements with those levers and exposed springs.
