Earl:

You are correct.  There is a photo of an all-steel Erie auto car (98506) with a 12-38 reweigh.  With a 3-year reweigh interval, the latest this photo should date from is the winter of '41-42.  Surprised to see the USRA car with an Ajax hand brake this early,  Might warrant a dive into the AFEs.

Interesting array of house cars in those photos, including two with a herald I didn't recognize.  I think they are DT&I cars, something I have not previously seen on B&M tracks (caveat: in pre-WW-II photos)
