>From the best I can remember there were Archbar and Bettendorf - equalized but not sprung.
Roller Bearing and Bettendorf - sprung. The sprung trucks were in the same mold as were the equalized trucks. For the longest time Russ had a TON of roller bearing trucks because the demand was for the Bettendorf sprung. Through a combination of making cars that used RB trucks and a little "who cares" Russ used up the overstock. Obviously the bolster is the same for the equalized and for the spring trucks but they are not interchangeable to each other. The was a brass grommet/ferrule that Russ put in the bolster hole to tighten it up for a 2-56 screw. There may have been a similar brass ferrule used as an axle bearing but that was changed to a Delrin bushing.
