I've been looking for an MTH/LCT 263 myself (Chessie version) and posted a "want" ad on the forum prior to York. Even willing to pay above MSRP for a new-in-box model. And, of course, I have scoured the Internet for that and a couple of other models that I don't yet have in my collection. Gotta say: MTH Lionel Corporation Tinplate, both O and Std. Gauge, is getting scarce as hen's teeth these days.
I do have an extra 11-6063-1 263E (Lionel Lionel Orange & Blue) that is new in box and never run or displayed, that I am willing to part with, but I would be asking the advertised MSRP.
