This is for an HO set, I found while dismantling my O gauge layout, in one box of supplies. I believe someone must have given it to me as a gift, not understanding the difference between O and HO, and I simply placed the box with my train stuff, never unpacking it. Here is your chance to acquire an unused, sealed set of more than 60 pieces, all in original boxes and bags, which although it is over 45 years old, has never been run.
