If you're registered on any of the bullseye forums you might post your question & pics there. I recall there was a bullseye gunsmith down south who made very high quality handgun bullet moulds, I used to see his moulds on auction sites from time to time, but haven't really looked that closely lately. He always seemed to cut his moulds for Lyman handles, and he really had quite a following in his day. You mould looks like one of his, and I seem to recall his were marked similar to this one. I just can't recall his name any longer. It's just been too long since I dealt with these moulds.
