Summary
The Jacobs Aircraft Engine Company began in 1930 in Camden, New Jersey, later moving to Pottstown, Pennsylvania where this engine was built beginning in 1934. It had was equipped with a battery and magneto ignition system, but had other features common to earlier Jacobs’s models.
Page Industries of Oklahoma acquired Jacobs in the 1970s, but only continued manufacturing aircraft engines for a few years. This military version of the engine, the R-755-9, powered the Waco PG-3/A; Cessna AT-17A/B/C; and Cessna UC-78/A/B/C. Other military R-755 engine models powered aircraft such as the Kellett YG-1 autogiro and Stearman PT-18 primary trainer.
