Great Northern bushbow. Not sure if Jerry actually calls it a flatbow. but it's deffiantly not a longbow. Description of bushbow from Great Northern website.....
"The Bushbow is somewhat patterned after the Plains bow of our Native Americans, with a wider and flatter limb measuring 1 1/2" wide at the fadeout and tapering to 9/16" at the string nocks. The deflexed riser is 16" long and measures a sleek 4 3/4" in circumference around the leather handle wrap. The limb tips on the Bushbow have a 4 1/2" power wedge, discreetly inserted within the laminations, which eliminates the need for nock overlays."
Kohannah makes a flatbow too.
