Yup.
This is to confirm that the N&W HC71 and HC71A classes were built at Roanoke using PS kits. N&W's had hatches with zig zag ribs.
NW 177001-177999 - HC71, Roanoke Blt PS Kits, Blt - 73/74

NW 185000-185074 - HC71A, Roanoke Blt PS Kits, Blt - 1973 (HC71A has additional Round Loading Hatches built into trough hatches, dischg gates have extra bracing)
NW 178501-179000 - HC78, Roanoke Blt copies 4750, Blt - 1980 (these have "arched" roofs)
(got most of this info from a Russ Goodwin email on the NWHS mailing list)

Pullman did not supply kits. They supplied the roof components (except for the side plate angle, roofwalks, roofwalk supports), and other than the outlet gates, hatches, etc, the rest of the car was fabricated by Roanoke Shops. Not all roof hatches had 'zig-zags'... the cars equipped with General covers were either ribbed (177001-178000) or smooth (178001-178500). Rockwell (177001-178000) and Landreth (178001-178500) covers had the patterns.
