Here is another refrigerator car, SLRX 4216 at Terminal Island in Los Angeles in April 1958. What type of trucks are these?

Richard Wilkens

Those are National Type B.  Originally offered by Proto2000 in HO.  Now sold by Walthers and mislabeled as a National B-1.

The trucks are National B-1.

Attached is a National Malleable and Steel Castings Co. ad from the Aug. 30, 1941 Railway Age, showing both their B and B-1 trucks.  A noticeable difference between the two are the bolster ends.  Also the springs on the earlier  B truck were larger diameter than usual and as the capacity increased so did their diameters, but the wheelbase stayed the same.

P2K/Walthers offers the B truck, while Athearn and Kadee sell the B-1 truck.

This afternoon I tried downloading this scan into both Files and Photos, but neither would accept new additions.  If interest in seeing it, just contact me off-list at brianleppert at att dot net.

Athearn and Kadee sell the B-1 truck.

    I looked up the Athearn B-1.  They want $23 for 2 pair, this seems really high!

What kind of roof is that?  It looks kind of like it has two raised parts for each section.  Diagonal panel perhaps?

Can someone post side-by-side pictures of the National Type B and Type B-1 trucks? Pointing out the differences would be helpful, also.
Thank you.

Brian did that yesterday in this thread.

Tim,

Thanks for the correction! 
I learned the difference from Brian Lippert's post of the National advt shortly after I made my post.
