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.

In the last photo are Soda bottles sold in the seventies these do work in the OK Cub but only the eight gr. bottles many are larger and will not work.

So Meflood which type of engine do you have does it have the extra filler/charger line on the tank or does it have these high pressure bottles?
