Most, if not all, of the boxcars owned by the Wellsville Addison
& Galeton carried hides. Pics of those cars at tanneries on the
WAG do exist, especially the big one at Elkland, the loss of which doomed
the WAG. Yankee Clipper offered an HO kit for a WAG boxcar.
Most of those cars came from the B&M. I run one on my layout
even though I do not have a tannery.
