Bench tested this now & it runs perfectly! To see it run, search YouTube for. "S SCALE BRASS SUNSET MODELS UNION PACIFIC 4-6-6-4 CHALLENGER NICE IN BOX UP RARE". Only made one year, one run, 1987 by Dong Jin.
The only modern brass S scale UP Challenger made! Small detail parts were snagged by the foam over the years & came off the model as the photos show. They'll be included in a parts bag.Other than that the overall condition is nice. There are a couple areas of minor tarnish as well. Also there is a small dent on the boiler as the picture shows. Model has lived its whole life in the box and original foam its very nice condition save for the minor condition issues it has.
I dont think any parts are missing. Just the previous owner had it in the foam without using the plastic and the sticky out parts of the model got snagged on the foam. When taking the model in and out of the foam over the decades.
If you look at the pictures of the bottom of the engine and tender they look like maybe never ran on track. The top foam pieces are included, just not shown in pictures.
