I just recieved an old rocket motor off of eBay. Sometimes refered to as JATO motors (jet assisted takeoff motor) or by the more accuarate acronym RATO (rocket assisted takeoff motors) these small motors have always caught my interest. Mostly because they were among the first, if not the first, rocket motors that were mass produced. The urban ledgend about the guy that attached several of these to his car doesn't hurt the appeal either. I can't find much information about this particular motor, so if anyone knows anything about them I'd love to hear from you. The markings on the case read Rocket Motor M3, Lot PA-79-9.
