Hi
I've seen that movie a few times, and I've never bothered to notice what the Cavalry was carrying. It is odd to me that they were carrying 1860 weapons in the mid-18 70's. I also didn't note when Quigley was supposed to have taken place, but it had to be at least 1875 minimum. The Sharps had to have been invented, and he had to have gotten famous with it. Chuck Hawks says that the 45-110 was introduced at the end of 1876. That would make it 1877, even the British should have had their Colonists better armed at that point.
