N Brass - Pennsylvania RR S-1 6-4-4-6 #6100 Oriental Limited Samhongsa - FP MINT
You are looking at a gorgeous model of a very unique prototype. This is the locomotive that ran on rollers at the 1939 World's Fair. These models do not come up often. The model is Factory Painted and appears nice. There is however a small smudge on the engineer's side of the nose. You'll be very happy running this model at any N trak event.
The model appears to be mint except for the one smudge (visible in photo 11).
