W.A. Whitney Punch & Dies Diacro Di-acro, Roper Ironworker? Round, Oval, Square
I don't exactly know what machines these fit, I was told they might be interchangeable, or modified to fit.
Many sizes and shapes smaller size (up to 1in.) $25 a set. mediums (up to 2.5in.) @ 45 a set, and large $65 is set.
Come get all for $1,500!!
I can offer shipping, shipping cost would be dependent on size weight
