Hi
A fellow I know named Ed McLaughlin built one that took him
to the national science fair. I don't know if it is the same
one but this was in the early 60's some time.
Timeframe is about right, but my experience wasn't Ed. I suspect that the
design was fairly popular for science fairs. I recall that the Museum of
Science and Industry in Chicago even had one around that time. It was a
great "hands on" display!
