I was looking through Morning Sun's digital pub
Lehigh Valley - Best of Bob Wilt Vol 1 today and ran across a picture on page 90 with an unusual (to me) covered hopper. Can anyone help me find better images of the car (or another in its class) immediately behind the loco in this pic taken at Allentown PA in 11/1966:
I remember Chessie system having Centerflow-like tops for straight side open hoppers in the 70s/80s, but this car pre-dates that idea and it looks like a covered hopper that was, well, re-covered. Any help is appreciated, especially better photos.
Thanks,
Bryan
