the ones homer sells doesn't look quite the same as the old Bob young head, I'm just looking at photos though. the Bob young head looked to be heavier for the size, and the humphrey's head looks more concave up front and possibly shorter in the nose. I saw some very good pics the other day of the Young head and can't remember where I was on the net when I found it but the top and bottom edge of the head didn't look like it tapered down toward the front much if any, the other two versions I have seen pics of do taper like this. I'm gonna make one or two one cavity molds for a head like Bob Youngs when I get the chance by pressing a blank steel copy of the head I want between two pieces of soft aluminum aligned with brass pins, the trick is to make the blank as perfectly symmetrical as you can, gonna have to figure out the best way to grind that bevel on the front accurately so it will track straight.
