John, Interesting, the unit I have has 12 and 24 inch extension rods. It was invented at Overbrook in the very late 1940s. A friend of mine who went to that school in early 1950 made them. I did not know that there was a similar product on the market. I wanted to have mine duplicated so that I could send the original to the school for their museum, but it would be very expensive. I did make some photographs for them. Do you know how much the rotomatic costs and is it 3/8 all thread? If it is not too expensive and does the same thing I would consider getting one and donating the original to the school.

Sounds close to a rotomatic. The rotomatic come with 3 extensions, 6, 12, and 18-inch. Also, one can order the extensions separately. earlier, Lenny McHugh, wrote: >Hi All, >I use two tools for measuring.
