Last week I was talking to a friend about model railroading. He told me he worked for Air Products as an designer. He seen a Pennsy caboose on my shelf, when transporting a heat exchanger by rail they would ride in a caboose like that one that Air Products owned. He sent me some video's of some being transported. I thought it would be nice if I could find a caboose and give it to him. I checked the bay and found a HO Air Product caboose.
