KC, There were many many kinds of CL kits back in the '40s and early '50s, especially in the CL world. Back then CL was something you could find flying in almost every school yard and park. Those old spark ignition engines did not put out power like even the older glow-plug engines, so an ignition .19-.25 was mounted on a model that a like size would have at most an .09-.15 today.

Many kits had different types of wood and wound up very heavy. Mostly, but not all, scale-like kits turned out very heavy and just flying around in circles was the ultimate result. I have several old kits and if the modern day kit-builder could see the condition of the wood of those days, they well may just trash it.

You can keep them, build them, or sell them on eBay. Unfortunately the number of collectors are disappearing fast. That is proven by the large numbers of old stuff now available, which is going at rather low prices. The current fliers rather have a good old-time design kit from one of the many producers of old time designs with current good wood and laser cutting.

Good Luck with whatever you choose.
