NYC Boxcar question


Geoffrey Barbier
 

Recently bought a print, and found this NYC boxcar with an almost perfect numeric progression as a number, hiding down in the corner.  Would love to build a model, but you can't see which ends or which roof.  Is there any way to determine which version of door and roof to use?  The photo was taken '59.

TIA!
