It is now apparent that this a a modified and detailed Williams E6s. I found internet pictures of the original Williams and compared them to mine.
Up first are two side views: the original, then mine. The shortening of the pilot platform is shown. Note, too, the changed bell, changed whistle shield and the piping below running board.
Here, on the red background, is the 3 rail frame (or two rail as well, I guess). The next two clearly show how my frame was cut.
Last two are of running gear. The overall view shows that bent reverse gear cross carrier. The second shows the name on the gearbox as "SAM Korea", indicating a Samhongsa build. The cylinders are in fact on the driver center lines. I understood some of the Williams engines had the cylinders raised.
