According to the car diagrams, these are the trucks for the SM-19 class:
SM-19 class series 52000-52149. CB&Q truck type 62 which is a 40 ton
steel double-truss Barber Lateral Motion (Spring Plank).
SM-19A class series 52500-52699. CB&Q truck type 80 which is 40 ton
Scullin Self Aligning (Spring Plankless) truck.
SM-19B class:
Series 52700-52999. CB&Q truck type 54-A which is 40 ton Andrews type
cast sideframe. Specifically states in truck diagram this truck replaces
Arch-Bar trucks. The journal boxes could be reused from Arch Bar trucks
with this sideframe. I suspect these journal boxes were reclaimed from
scrapped cars with Arch Bar trucks considering these cars were built
post World War II.
Series 53000-53099. CB&Q truck type 76 which is a 40 ton Barber S-2-A
(Spring Plankless) truck.
Series 53100-53199. CB&Q truck type 77 which is a 40 ton ASF A-3 Ride
Control truck.
SM-19C class series 50500-50599. CB&Q truck type 79-C which is a 50 ton
Scullin A-3 Ride Control (Spring Plankless) truck. This was a double
deck car series.

"Bob, there are two issues in this thread, one is the CB&Q Andrews
truck, which is a 40 ton truck, and the other is the PRR Crown truck
(resembles Andrews but larger) which is a 70 ton truck (Crown also
made 100 ton trucks for gondolas and hoppers). The Q didn’t use 70 ton
trucks under stock cars. Besides Andrews 40 ton trucks, the CB&Q used
Barber double truss lateral motion spring plank 40 ton trucks on some
SM-18 stock cars. I don’t have information on the SM-19 stock cars
immediately available, but I’m pretty sure they had 40 ton trucks,
probably double truss spring plankless on most cars, but I have one
photo of a SM-19A with Andrews 40 ton trucks taken in the 1960s (3-6?,
the second digit of reweigh date isn’t legible). It has the modernized
lettering, and probably Chinese Red paint (hard to tell because it’s
heavily weathered). Chinese Red wasn’t used until 1959, so that
supports a 1960s photo data. I don’t think the CB&Q ever used Crown
trucks."
