Gumby

Where's Mr. Bill when you need him?

Rick

Kusan FA-2?

Yeah, and Kusan track.  Also a Flyer steam engine w/o tender.  Spotted some classic old Dinky Toys too, including the Coleman crane truck.  First time that I saw this episode.  I remember another when Gumby took a trip on a Marx train. 

BTW, the popular nickname for cold water survival suits is a Gumby suit, 'cause you look like Gumby when you wear one (except you are orange, not green).

Another one:
