It is a very interesting Colllector piece.
This is not meant to nitpick, but the General Models switcher that survived into the All Nation era is a model of an NW2, not an SW. it is not too bad even by todays modeling standards. It is based on the early prototype without louvres in the doors. I especially like the notched hood in front of the cab which disappeared on the SW series. The hood is too wide I think, but not grossly so.
General Models also offered a model of an "SW" switcher. The prototype was a cross between an SW1 and an NW2 sort of. The hood was shortened because it was only 600 HP, but the cab sat back in the same location as the NW2 on the same frame. It is a fairly rare prototype too. The SW meant 600 HP, Welded Frame. It was easy to create a reasonable version of this for the times using the NW2 casting and chopping the front of the hood back a little. This is a rare piece. I have seen 2 of these. I saw a complete kit at a Hobby Shop in Kansas City back in the 80s. I saw one on a table at a show built up that I think was also made from this kit. The kit included parts to finish the front somewhat like an SW-1.
