The Chicago & Western Indiana RR had several Haskell & Barker, 40 ft, Wood Side-Dump gondolas. Some were still in use in 1960.
#1185, built in 1913, was at the Illinois Railway Museum the last I saw. (Poor condition)
Does any company make, at least a close HO model of these cars. Can't find any yet in my searching.
Thanks, Paul Hillman
