Had in mind to build a "Killdeer Rifle", as I like the long look---understanding that it might not be PC or HC, but a nice Lehigh with the long barrel has appeal to me. So in 2011, I called Wayne Watson to get his best recollection on the Killdeer rifle and the following notes were from that converstation:
Barrel was swamped .50 caliber built by Getz (1 1/16 at breech, 13/16 at mid, and 7/8 at muzzle) 50 inches long
Lock—Small Siler (made gun look even longer) (Mann wanted to make the gun look as long as possible)
Triggers—Davis
Allentown School (Rupp), with all iron furniture (Rupp buttplate, Isaac Haines trigger guard)
Stock stained light ( Brian Lemaster and Wayne worked together on the stain on this rifle and
some of the other rifles from "Last of the Mohicans") Wood had curl (wide spaced—light) similar to a John Beck.
So. you can see that it was a hodgepodge of parts, but I still like the long look and had Ed Rayl build me a barrel in the same diemensions and Ihave a stock blank to build a left-handed rifle using an early Cochran left-handed flint lock. Should be fun to do and to shoot.
Never found any clear pictures of the original rifle.
