Vintage AHM/Rivarossi HO-scale Union Pacific No. 3967 Challenger steam locomotive with matching Union Pacific centipede tender. This articulated locomotive has the distinctive 4-6-6-4 wheel configuration and is commonly cataloged as Rivarossi No. 1591 or AHM No. 5113-02.
The locomotive and tender have not been tested and are being sold strictly for parts, repair, or restoration. No guarantee is made regarding the motor, electrical components, lights, or overall operating condition.
The set presents well overall but shows dust, scratches, finish wear, and other age-related marks. The front pilot/truck is turned or displaced and may require adjustment or repair. The tender’s rear coupler appears to be missing or replaced by a bent wire loop. Some small handrails or detail pieces may also be bent, loose, or missing.
The sale includes only the locomotive and matching tender shown. No track, transformer, original box, paperwork, or additional accessories are included.
Please examine all photographs carefully for the exact cosmetic condition, completeness, and contents. Sold as-is.
