I was able to purchase the entire lot of equipment which included a Herters Super 81, Hollywood, and 2 Potter Duplex reloaders. As I understand ( I have only heard cursory information), Potter manufactured from the 40s to the 60s. They also made a press called a "Gem" and one other (I think). They also made a lead hardness tester, ingot molds, and electric lead melting furnaces.
I was hoping the seller had pamphlets, instruction manuals, etc. but no luck. I'll be interested to get a close look at the equipment and the little accessory items he includes.
