I was thinking in an earlier time frame than the RMFT I believe the 24" guns were in the 40's or 50's,and I suspect many guns were cut down just to the point of being functuional,this was likely the norm rather on the frontier than the scaled down versions we have today, a cut down gun looking like that would likely be the exception to the rule,another case of where and when but for newcommers as much of a reliable version should be presented as we possibly can about these guns as they always pop up and many new ML shooters shy from the longer barrels,like to see them have as much info and thoughts to chew on as possible.I am always reminded of a couple of gentlemen who had purchased fairly expensive C or D French guns only to become quite unhappy when an indepth thread was started about these guns and the locks and actual meaning of the lettersused in the gun description, one fellow had requested a trade lock and was told by his builder that the Germanic lock provided was more correct,that has gotta hurt, though I do suggest a lot of personal research and not relying on any one vendor or builder(with a few exceptions there) for authenticity info about gun types.
