Here is sort of a Pit River Style bow. It is Yew with sap on. It has two courses of deer sinew on it. It is 46 in. ntn. 1 3/4 in. at fade outs. At the nocks it is 3/4 in. It has a 5 in. brace height and it pulls 55 lbs at 22 in. Everything is all natural except for the bowstring. I didn't really intend to make a Pit River Style this is kind of what it came out to be. If I was actually going to do a Pit River Style, it would be reflexed. I don't know if they had a flat bow design but we only get to see a glimpse into the past, so, maybe, maybe not. Thanks for looking John.
