Something I became very interested in recently are older Norfolk and Western locomotives, and unshrouded N&W locomotives in particular. The J-class seems to be a staple model of the hobby, and it doesn't seem hard to find a few different iterations of both the Y and A classes. I've found a few 0-8-0 switchers from MTH here and there. But beyond that I really haven't found any models of previous N&W prototypes. I'd love to get my hands on a K3 (never shrouded), wouldn't mind an (un)shrouded K2/K2a either. An N&W 4-6-2 would also be nice to have.
But I never seem to find these. I think 3rd Rail produced a handful of K's a few years ago. Apparently Lionel had a cancelled production run too. But it seems that no one else has made them. Is this true? Are there any 4-8-2 models out there close enough to a K class that, if they were repainted and lettered, could pass for a K?
