I did see this last week, and again last night. Very interesting fellow - how many folks do you know who collect buildings? Real buildings? I thought my[i/] collection took up some space.
Anyway, in one of his buildings, there were two horse-drawn hearses and a horse-drawn ambulance. They showed those briefly, with the hosts of the show making the usual jokes ("Duh, ya think the hearses are haunted?" ) and they ring the bell on the ambulance. All three look in great condition.
It would be good to know more about these (I didn't even catch the state, thanks, all). If someone has any more info, yes, it seems he might sell stuff (that's why he was on the show, after all, wasn't it?)
Bee, it was not a Civil War military ambulance. Looked to be a civilian, fully enclosed ambulance. I have no idea what make.
