HO Brass WMC Westside Model Co. UP Union Pacific 4-8-4 FEF-2

Item was purchased new in mid 70s. It was never run but used as a shelf display. After all this time, I do not know if the locomotive runs or not. One 'number display' on left front next to top headlight is broken but the broken piece is in the box and could be reattached. Another top small piece on the left side in front of the cab is broken. That piece is missing. The box is in good shape however the foam cushioning inside the box is showing and acting its age.
