Northern plains bow... 43" long and a little over 1-1/2" wide at the handle. Maybe Blackfoot. Probably for war or hunting buffalo at close range. The snake skin is rare. If you can determine the type of snake, you will probably determine the place of origin. Southern plains bows never had snake skin backing (bad mojo).
The handle wrap looks like it's holding some horse hair that sticks out on top and bottom of the belly side. Very common to have horse hair decorations on "horse" bows.
The low brace height was common. The string typically does not have a lot of tension at brace on these bows (so that it could be easily braced while riding). The wrist slap is, therefore, not too bad. It says the string is made of bark, which probably means that the string is not original. Another clue that the string is not original is the fact that the top loop does not slip (like a lasso knot).
