A half-stock J&S Hawken flint rifle? No such thing ... maybe. No one knows for sure.
Tom Watson, Sr. built this originally as a .50 1:66 for me, with a Rice 1"x36" radius groove barrel, but I changed my fickle mind and shipped the barrel off to Bobby Hoyt for a makeover as a .54 1:60 w/radius grooves. Barrel is left in-the-white, as I prefer. Chambers-SIler late Ketland lock, Pecatonica figured maple stock, steel furniture, L&R double set triggers. Came to me in-the-white and I stained the wood with 2 coats of LMF American Walnut, CYA'd to seal the barrel channel and lock mortise, three coats of warmed TOTW Original Oil finish (linseed oil w/driers), and finished off with multiple coats of warmed Tru-Oil varnish. Tapered 7/16" hickory ramrod. All in all, not too shabby a rifle that's 9lbs 5ozs total weight. Will cone the muzzle today and shoot 'er in tomorrow. Still not sure if this rifle is "the one" for me. Maybe, gotta see.
