On the way back from the range yesterday, my buddy and I had to stop at his smith for a pistol part. Talking rifles with the smith got us invited in to see his private collection. He had Sharps, Spencers, Winchesters, Martinis, rolling blocks, falling blocks, top hammers, side hammers, no hammers. He had a couple of hundred museum quality pieces of 100+ year old treasure. It got me thinking, ( since he only had H&R handguns ), What did H&R rifles produced in the 1800's look like? How much has the design changed over the years?
