I had a pair of these when I was a kid and I swear they are still in my
parents basement somewhere. I will be back in Fairfax (VA) in a couple
weeks and will continue my once a year quest through the quagmire (my
parents have lived in the same house for about 25 years so they have about
25 years of junk down there) that is their basement to find my missing
baseplates! They were always the basis for my town as a child.
