I guess I came close. I have four K4s of Scale Craft origin, and plan on a fifth with the original 1737 look, including that ridiculously small tender.
The riveted long distance tenders all had six axles, but the welded ones had the eight axle configuration I show here. There is a set of Lobaugh side frames for these trucks on eBay right now, for reasonable.
Here is an example of a stock Scale Craft K4 - note the blind center driver, and the incorrect counterweights. This is one of the better examples, since the builder (not me) chose to drill and place small pins in the smokebox, instead of the more common ugly nails or riveted overlay strips.

Also note the lack of a flange on the sand dome, where it meets the boiler. Any time I work on a Scale Craft, I fix that little detail. I do that on Lobaugh tank cars as well.
