This is based on rifle #19 in Shumway's Rifles of Colonial America volume 1. The original is walnut stocked, has an octagon to round smoothbored barrel of .54 caliber or so, has no particular "school" features, and no parts or features that would necessarily date it to after 1770. Shumway thought it was likely made in the 1750's-1760's but it could have been made later, obviously. I had John Getz make me a custom barrel profiled off the original, and he rifled it for me (I wanted a rifle). I agree 100% that having an octagon to round, rifled barrel is not normal" or "common" for the period. The stock is Michigan walnut, the lock a Chambers germanic, reshaped a bit to have less curvature, with a little filework on the tail. The furniture is highly modified from commercial castings. I pretty much replicated the original dimensions with a little tweaking to have it fit me perfectly. I'll also post this under the historical area for discussion there. Critiques are welcome. Years ago Ron Luckenbill did a stellar re-creation of this rifle and that served as inspiration for me.
