Although these trucks are based on prototypes cast by GSC/Commonwealth, Kato calls them "Budd" trucks. I'm told that they are based on a GSC 41-N-xx design, just with the top-side detailing removed so that they can be used under skirted cars. They feature a single drop equalizer and disc brakes (as per post-war practice).
