EJ&E twin hoppers

Richard Townsend

This photo, taken in Longmont, Colorado, has an EJ&E twin hopper in the background, adding more to the mentions of roaming hoppers:
Can anyone provide some information on these hoppers? Who built them and when? Is there a model in HO that would at least approximate them? Is there a source of appropriate decals, assuming a suitable model could be found?
