The only issue I have with the NRA video is at the end they state most of the early rifles that made their way west were stamped Hawken. Most of the "plains" rifles were of other manufacturers as they cost about 1/2 of what Sam & Jake got for theirs. If you had the money after getting outfitted with food, clothing, lead, powder, traps horses, mules and all the other sundry items needed if you could afford it you would get a Hawken. Just a small point of fact. As to there not being any surviving examples of flintlock, there had to be Sam & Jake were set up and were doing business before caps were readily available. They were some of the earliest advocates for cap locks and most of the flints either didn't survive or were converted to percussion at a later date.
