We've talked about iron vs. brass mounts bring pc on F&I period firearms, but there is one more thing I would like to clarify. What about the "poor boys" without buttplates, nosecaps, or toeplates. Do these date from the pre-revolutionary period, and are they purely southern mountain rifles?
No easy answer.
Existing original "Poor Boys" as most folks think of them, Southern guns with no buttplate, nosecap, toeplate, almost all date to the 1820's and later, based on the locks and barrels used.
There are at least 2 examples of early guns with iron mounts, believed to be made in the South, which have some iron furniture and are not completely fitted out with all the bells and whistles. And there is an iron mounted, blacksmith-made (in my opinion) rifle with all the trimmings, crude as they can be, that could date to before the Revolution. It is featured in Kindig's book and, I believe, Shumway's RCA #2?
Then there are Pennsylvania "barn guns", "schimmels" etc which appear to be largely confined to a small area of SE Pennsylvania and to date to the early 1800s. These lack buttplates, nosecaps, patchboxes, etc. I believe they were farmers guns, not hunter's guns, just as a farmer or a kid might have bought a single shot .22 JC Higgins for the barn in the 1950s, but the hunter bought something nicer.
Of course, folks reason that "sure there were plenty of poor boys in the 1760's, but they all got used up and thrown away cause they were not fancy."
It is interesting, in these debates, to consider that the Native Americans would not settle for such stuff. They wanted and paid dearly for fully appointed guns. Look at all the trade rifles and you'll see what I mean. Even the Northwest gun has a buttplate, and that gun was about the cheapest thing around. That makes it harder for me to accept the "economic argument" that common every day folks could not afford a fully appointed rifle and so there was a big demand for poor boys. Folks maybe also forget that the barrel and lock cost a lot more than the rest of the gun, and making and adding standard parts was not a major part of the cost of building.
