Upon further investigation, I still I am not sure what I have. Jimmy is the producer, no mention of Peter. There is no 'So Mote it Be', but on the side that had the inscribed 'do what thou wilt' there is another inscription that says 'Mastercraft PF', all the other inscriptions are obvious done by hand, but those two are in cursive script. There is a lot of hand-gouged letters and numbers that mean nothing to me.
I tried to take a pic of the inscriptions in the vinyl but that has proved to be all but impossible using my iPhone.
Thanks again, Steve, I appreciate the information
