Too bad the patchbox engraving isn't visible to any degree. From the few Bucks Co rifles I've seen, and the one I own, it seems the engraving is all a bit different, and attributable to individual makers. Same with the carving to a bit lesser degree, but they all seemed to have a little personal touch they used a lot.
The carving details are close matches to those on my Weiker rifle, but the thumbnails on the trigger guard and butt plate aren't, and the side plate is not a match either. On the other hand, my rifle is attributed, and not signed.
I'd bet someone here, or someone that used to be here knows the whereabouts of this gun!
By the way, I have a non Bucks Co rifle with the same style not so handsome percussion hammer conversion on it!
