There has been some mention here regarding TR's '76 rifles. I had a chance to see some at the visitor's center at Theodore Roosevelt National Park at Medora, ND a few months ago. I took some pictures, but, of course, they are behind glass, so these are not quite suitable for a coffee table book. Hopefully those here will find interest, though. I've also had to reduce the file size, so the quality isn't super high. Lastly, my phone camera didn't perfectly focus, so some detail is lost there too.
There were three rifles on display. To keep them straight, I'm going to try to make separate posts for each rifle. The first two are nearly identical -- they are guns that TR brought with him hunting in Dakota Territory. He gifted one to his later ranch manager Bill Merrifield. He had a plaque added to the stock of that rifle. It is in .50-95 caliber.
