This is great, I love threads like this. Yes, I have mine. It's a Lionel Scout set and it's a curiosity because it matches no cataloged or uncataloged sets. There is one cataloged set, the 1609 from 1959, that it could be if my parents had bought a couple of extra cars to go with it, or maybe the dealer threw them in to try to move the set because it was old stock. It consists of a plastic 246 loco with headlight and a serrated bottom motor, a 1130T tender, a red Airex 6014 boxcar, a black 6175 rocket car, a blue 6162 NYC gondola, a coral 6476 LV hopper (which I just read was produced only in 1958 and is hard to find), and a 6017 caboose. I received the set in 1960 (or 1961 at the latest; I was 4 or 5 so I don't exactly remember anymore.) I had all of the cars from the beginning. The two cars that don't fit in are the 6175 and the 6014.
Right here in my attached image is the main reason I wouldn't consider switching back to HO scale, which there was a recent thread about. I don't do it often, but the set runs fine on my new layout. Is that fun or what?
