"1951 (single year) Jensen #10, with round magnet style generator machined from a single piece of cast iron, solid cast iron engine, cast flywheel, plywood base, electrically heated. Transition design of generator between prior horseshoe magnet style and later 3 piece magnet style generators. Made only in 1951 as a solid round form...quite rare given short production period"
