Default RE: CO2 powered engine

I made some new pictures of the OK Cub and the steel bottles.

At first there was nothing but the surplus military bottles avaliable and those were all painted O.D. green with federal stock numbers on them. At my favorite surplus haunt on Colorado Blvd. in Pasadena, middle to late fifties the bottles were 5 cents each. There were even cheap starters sold for fifty cents that was a spring pin that drawn and released poked a hole in the nozzle and you had a little rocket engine. We usually just strapped those on a chuch glider or something like an AJ Hornet.

Yeah, I still hae one of those CO2 starter "guns" Mine use a steel phonograph needle for the firing pin. Good luck finding those needles now. We ran the CO2 bottles in cars. They seemed too heavy for planes. We used a Jetex 50 in the Model 74 (?) in 10 cent gliders. Last I priced the "Sparklet" type CO2 bottles, they were like a dollar apiece. Reissued Jetex fuel is probab ly a buck a pellet now??
