Bill Cramp's Custom Erector Robot

Hi All, Doc here. I recently received these great photos from G&G reader Bill Cramp. Talk about a "blast from the past!" Looks familiar, doesn't it guys? Thanks, Bill, for the trip down Memory Lane.

Bill writes: "This is an original I built with the 10½ Erector set in the early 1950s. It was animated, rolling across the floor with swinging arms and illuminated eyes (unfortunately picture glare masks the light sockets and bulbs). I thought you might enjoy."
