Thank you, Brian,toggle quoted messageShow quoted text
It's wonderful to have that aha moment. Now I have better understanding of these trucks. Spent the night last night going over prototype photos of cars with National trucks.
I will be making changes to a fair # of cars using the P2K Type B's with a little carving and the addition of some TMW brake shoes. Frees up Athearn B1's to use somewhere else.
And now I will have a better eye when looking at photos.
Looking back in the archives, there are posts on the B/B1 trucks but I missed the full import of what was posted back then.

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.
