The natives that made that style of bow put the arrow on the right side of the grip, and shot a sharp left cant. The flat handle was made to flip away from the arrow upon release with the way they held the bow with their left hand. I made 2, one was sinew backed Black Locust 40 inches long, and the other was a 50 inch sinew backed Hickory bow. 17 ,and 20 inch draw, and 40,and 45 lbs. . I tried their style of shooting, but couldn't draw the bow far enough, or hit very well their way. I shoot them with a sharp left hand cant with three fingers under with the arrow on the left side of the grip. The Wintu, Karok,and Yurok, and other west coast natives made their bows more narrow over all compared to the Hupa tribe which is what your bow resembles.
