Cool DD SAL 40' AAR box car

I???m unaware of any other house cars using ends of this unique 4-4 MVC Carbuilder design...
Dunno if refrigerators count as house cars; but the ends on Armour 1-2000 seem to be of the same general design (in a R2/4 configuration), including the little squarish nubs at the corners between the ribs.
