It looks like the same cast zinc alloy from the photos I've seen so far, which doesn't make it a bad material, its used for a lot of other bridge brands. They had it cast too thin on the older bridges, so they bent, but that hadn't been a real problem for a while. They avoided the whole problem on the V2 bridge by using a separate string retainer to take the string tension. Pot metal is a generic term now, but usually means zinc with other stuff added to give it some strength, the "other stuff" being pretty variable. The Badass and similar bridges were Sintered metal, which is zinc dust pressed into a mold under high temperature that fuses it together. It has high compression resistance, but doesn't take tension well. Cheap trophies are a good example of cast or sintered zinc, but it doesn't have to be that cheesy if its used properly.
