IN the first photo, the NP 100 is a model of an "SW", not an SW-1. On the SW-1, the frame is the same length, but the cab end of the body is also moved in toward center as on the radiator end. There is a large "porch" at both ends.
Many Years ago, in the 1980s, I was working on a project in Kansas City and was visiting about once a month for a week at a time. With time to kill in the evenings, I found Spotlight Hobbies. They had a large stock of old-new O scale and recent build O scale. There were a couple of GMC kits on the shelf and i looked them over. One was the SW model, one was an NW-2. I didn't buy either, opting for a PRR C1 steamer from USH instead which was new in the box. Later I kicked myself for not buying the SW kit because I thought it was an SW-1. Then I learned it was not and I thought is was an imaginary model. In the early 2000 I got interested in trying to figure out what it would take to make an SW-1 out of an AN/GMC NW-2. In my research I stumbled onto the SW prototype. EMC(before GM/EMD), built that model as their 600 HP version along with NW2. A few railroads had them, including one on PRR. The bottom line is that the GMC kit was/is a pretty good version of SW locomotive. It has the sand box on the front like the SW-1, but has the cab placement/hood on the rear like the NW-2.
I think it is a rare model. The one in this thread is the second one I have seen.
