Bruce,
Yes, the one holding the tiny bulldozer is one of them. Nice catch on the other pix. You have a very intimate relationship with the photos on DPL's Western History Department. And, no, the flats at dismantling time on the RGS were not in that run of log cars. I have yet to see the MLC ordered log cars appear in a photo at McPhee. As far as I can tell from pix, the arrangement was to remove a floor board of the cut down gons that would, side by side, contain a pair of rails with long, vertical U-bolts ( maybe the leftover hardware from the gons) probably attached to the queen post boards, that could hold on the ends another single vertical rail with most of the base torched off; a hole drilled for an, at least, one inch pin on which the movable side would pivot. This is the way I soldered the brackets together for my models. If you find any more pix, especially the one of a stock train pounding upgrade in M.P.2, with a far off view to the right of all the newly refashioned log cars on that long, leftover spur. My view is they were stored there awaiting delivery to the MLC.
