From: geofross Have been quite a few of these engines on E Bay recently. Going for good prices too. Considering that they were not the finest examples of the Brass Builders Art, the amount of money they bring amazes me. I bought my first one for $150 and the dealer was glsd to get rid of it. This was in the 70's. The engine likes to shed parts as it limps down the track. Be aware that NPP had a recall of sorts for these engines. They offered a replacement front truck so the engine could negotiate 24" curves. The original truck shorted out on just about any curvature. The original truck was attached to the screw holding the frame to the boiler. The replacement is hung on a spring arm attached to the plate holding the drivers on. Make sure you get the replacement front truck if you buy one and want to run it. FYI for whatever it is worth.
