Similar patchbox on page 39 ,383 in Chandlers s Patchbox book.Peter Angstat on the first one..The one on page 383 does have expanded panels though, but finial is similar,made by Watt..That finial you see alot..I just read a article on Contract Rifles of 1792/1807 by Flanagan that shows some simple two piece patchboxs, Makers include, John Demuth, J Henry,Peter Gonter, Dickert Gumph probably more...I wonder if some of the makers did not get this idea after seeing these contract rifles and figure we will put these on our working man guns????You also see the simple two piece patchbox on New England Rifles, but the finial is different...
