Haven't owned a 2-10-2 in a long time. Back in the late 90's they could fetch up to $2500-3000 in stock condition, but that price has comes down a lot like all other USH locos.
I hate to mention this, but the USH 2-10-2 doesn't match any of the UP TTT series locos. Quite a few items are incorrect, although it does give the overall feeling and appearance.
I only owned one 2-10-2 that was correct and I've been looking to repurchase it since I sold it in 1998 to Bob Hess. There was a write up about it in OSN about that same time. Came in 2nd to Louis Bartig at the March Meet in 1997. It was a heavily modified USH loco built by Peter Bassett, who owned the Model Shop in the UK. He made all the corrections, including pilot, pony truck, cab roof hatches, domes and more, plus added an opening smoke box door with scale hinges to show the complete and correct smoke box interior detail. Complete and correct cab interior detail too.
Because the interior of the smoke box was open he ran electrical wires (tiny coated armature wire) to the headlight and marker lights through scale size surgical stainless steel tubing substituted for the normal sold brass handrail. It was actually a very remarkable loco and had a lot more features, plus coasting drive. I was an idiot for selling it.
