That was interesting, a name Emory Snyder is familiar, not sure if it is the same person but the right area. The Emory Snyder I know about had a Thorne Gas-Electric set up as a mobile welding truck. Btw my last name is Thorne I'm not a close relative but have a 1930 Thorne G-E. A gas engine (Buda in mine) drives a electric generator (made by Hertner Elec. Cleveland, Oh) which drives a electric motor on the rear axle also made by Hertner. Electromotive.They were made from 1929-36 in Chicago & Cleveland.
