Clark, take a look at the Atlas 70 ton roller bearing truck, and
the venerable Athearn 70 ton roller bearing truck. They are both
quite similar in appearance to the Barber S-2 pictured in the
1961 Cyclopedia.

Thanks Tim, I will have my friend take a look at them.

Clark, the tonnage capacity and roller bearings have nothing to do
with the S2-A-0 (yes, that's a zero) designation. There were also
50-ton plain-bearing Barber S2-A-0 trucks. I don't disagree with the need
for the 70-ton RB trucks, only
commenting that S2-A-0 is not a sufficient description to get what you
want.

Tony,
All I had to go on is what is in Gene Green's CGW freight car 'color'
book. I thought the A-0 may have been for modifications to the S2
truck...dummy me.
