I've got a steamer trunk full of 50s vintage Lionel trains, track, etc. that I am looking to get rid of but would like to get a sense of what it might be worth.
And my personal favorite, the Rocket Car! I've got the car, the rocket and the gantry, but haven't found the launcher. Used to launch that rocket and it would punch through the fiberglass insulation in our unfinished attic.
Progress came in the form of finishing the upstairs with bedrooms and a bathroom, but no room for trains. Kind of like old motorcycles, these train "where running when they were put away".
