Model Train retail lot

Product Name: Model Train retail lot
Totally out of my element here…grandpa's scale train stuff, in storage since the 70's. Power packs, two engines, three building kits that look complete, and two building kit boxes that look to be bits and pieces. Twenty-five plus pieces of track, wooden boxes timber tunnel portal and compound house kits that look to be complete (never constructed), locomotive lighting kit, switch control box sets, steam whistle (inside billboard for Maxwell House Coffee), ballast, wiring and loose odds and ends in a bag. If I'm way out of the ballpark retail on the price, make me an offer.
