A different Gradua

The OBA 55 Zenith Gradua story is referred to again in the letter on Heron Heads in ‘Blow Your Own’ OBA 57. The attached photo is what appears to be a Zenith Gradua outfit, but note where the variable pulley is. Up front! A cursory search of the Net can’t find another example but there will be of course. The only clue to the photo is the family name Way, possibly from the Ascot Vale area in Melbourne. Maurice Austin Melbourne
