Any ideas on this sneaky pete? Hoping someone here may see it and recognize it as one they or a friend might have made. The owner picked this up a few years ago. Stamped "M" in the butt sleeve, radial pin, 58.5" and slim butt @ 1.19" and 0.820" at the joint. Worn satin finish. Dead straight and nice player...he is just curious who the maker might be. Thanks guys.
