Wouldn't mind seeing them done for the 800 cars BR&P got, but I doubt it very much.
I'd buy a few, but for at least $15 (Caboose Hobbies currently) a piece, plus new trucks and couplers,
that is getting pretty steep for a string of hoppers; for me anyway.
Those 800 went to the B&O around 1932 btw, as N-17b by my info.
