My dad bought a bunch of moulds at an auction, including two Lyman 358156s, Lyman 35863 4 cavity, two Lyman 429244s, a Lyman 358477, an Ideal 313445, and a Herter's 32154. Yeah, it was a pretty good haul. It more than makes up for the usual crap he buys and drags over here. I can use all of them except the 313445 and the Herter's. I can't find anything about either of them. Can one of you fill me in?
A couple of them have some rust on the blocks. What's the best way to get the rust cleaned off?
