Here is a new toy I just picked up.
Pretty typical W.R. 1871 in 577/500 No.2.
I must admit that I have a fondness for these rifles (1869/1871) and the 500 No.2 is such a fun round, I couldn't resist it. They are so Victorian and quite robust.
Interestingly, this example has Whitworth rifling and my two 450's are Henry rifled.
