That looks like a fun rifle.
My only experience with a rolling block was with a Navy Arms rolling block pistol, in .22 Hornet caliber, back in the late 1980's.
I've been looking at Winchester 1885's, but now I'm thinking of some of the Remington Rolling block replicas that come with double-set triggers.
A great video, I really enjoyed watching you handle that fine old Remington.
