Gary Holmes drew a squiggly looking crooked arrow on his bows, usually right under the specs...
Later I never knew him to identify himself on the bows as the bowyer when the Shrews came along...... unless it was something he was experimenting with, or a shrew that didn't make the grade, but usually he would remove the identity of it being a Shrew or a LaClair bow.
I've had a bunch of Gary's bows, and some early experimental Shrews and loved them all. I still have one of his reverse handle longbows.... my first custom order bow.
