I think the discussion is pretty well on the mark. Most were dirt-simple, but they could be examples of the leatherworker's art. As far as age, in Madison Grant's book there are some excellent illustrations of some of the earliest known (F&I War?) - including a very early one with a wool strap. I don't have the book here before me (Still at Day Job) but there is a photo of one that was documented to have belonged to a "professional" hunter along with the contents that were still inside. This individual (...now,this is from memory, so allow for memory loss after a hard day...) apparently shot game and sold it to various markets and other wealthy customers in that day. He would have used it day in and day out. His bag appears to have been professionally made, very plain, but excellent craftsmanship on par with a fine saddle or other high-end leather item. It appears like something he would have had a saddler or other leather craftsman to make. He was probably the exception, as he used it most every day, and it might have been the last one of many he wore out through the years. (It might have been made by the saddler because he reasoned one excellent bag would outlast 5 home-made ones. He may have been right - it still looks very good.) But, I make a few pouches now and then, and have looked at some very early ones over the years, in collections and at gun shows, and most seemed to have been made by the shooter in their "spare time", as on a rainy day when farm work was not possible, or simply using some leather (well tanned or otherwise) to put together something that would hold everything together. Madison Grant's book has every conceivable one possible. Many appear to have been user crafted. Most individuals back then had some connection with harnesses, saddles, and leather on a daily basis. Most farmers had some simple harness mending tools, and some ability. Most of the pouches I have been privileged to examine closely look like the sewer did not have a "stitching horse" handy as the stitches are crooked and irregular. (Like those I made (and make) when I don't have my "horse" handy) But, I have seen some that were known to have been made by the owner that were very finely made. In summation: They were as individual as the rifle they accompanied and the shooters who carried both. Regional differences? Probably. I never saw a double bag or a teardrop (heart) shaped one here in the South, and most were not lined. (But, I haven't seen them all. I might be surprised tomorrow) One thing is sure, most were probably the last one made while the rifle was in use, so considering the rifles sometimes had a working life of 50-60 years (or more) they might represent a regional style that was popular near the end of the percussion era, or when the rifle was "retired". Or they might not. If it is nearly unused but shows deterioration in keeping with the age of a rifle it accompanies, logic indicated it "may" be contemporary with the rifle. One never knows. I make fancy ones and simple ones. They all seem to be popular. Maybe the originals were the same. If you use original materials, original methods, and follow the same simple styles, I believe you will be pretty accurate. Campchair
