The only records I am aware of are:
Hubs - Howard Herz
SqinCir & a few DiSq - David Moore - HH also has some of these records.
USPC- Howard Herz and a few others.
H mold, Hourglass, and Lazy diamond exist but the price is too high in my opinion. I intend to take a look at them in NOV.
I have been getting a few DiCd and NV molds but I think that will be ending soon.
