Ted, is this for the first batch of B-50-25 with the "wide-seam"
doors, the second batch, or both?

It is designed for the wide seam batches built by Pullman-Standard and
Pressed Steel.

Ted Culotta

From my notes I show only one batch of PSC B-50-25's 20500-21499
and two batches of PS cars 21500-21749 and 21750-22249. (And two
PS batches for T&NO) Which ones had wide seam doors?
