To all those that responded,thanks.
I just borrowed back volumes of RMC and
found the article which is very informative.
Photos of the weathered or later lettering
scheme taken from the ground in less than
3/4 view seem to hide or soften the roof configuration.
The photo of restored car in Baltimore really shows it.

There is another photo I forgot about on NE Railfan site of B&O 295483
with re-weigh symbol and date of "RF 1-54" that had angles added to
re-enforce the side sills.

Also be sure to include, as stated in the RMC article, the angles to the
roof, which were there to help support the Evans auto loader mechanism
attached to the underside of the roof.
