This is a 1986 Overland Models, Inc. import, built by Ajin Precision Mfg. in Korea. The original box has minimal shelf wear and comes with spare and detail parts. The SD40X was an experimental testbed for EMD, using a new 645 series prime mover on an SD35 frame. This particular model represents Union Pacific No. 3043, featuring flared radiators like the SD45. It's painted in UP's Armor Yellow and Harbor Mist gray, with glazed windows and lit lenses. It's a great example of Ajin's early build quality. This tank drive model runs smoothly and quietly.

When handling the model, be gentle as it's a brass model and can be fragile. Also, avoid dropping it or subjecting it to rough impacts. For maintenance, keep it in a clean and dry place. You can use a soft, dry cloth to clean the exterior. Check the wheels regularly for any signs of excessive wear or dirt.

When storing, use the original box and foam insert to protect it from scratches and damage. If you have any issues during operation, refer to the control settings or contact the seller for assistance.
