Red Max

These are not RC products, but they are toy grade wind up gliders. I bought three of them at an antique store. They are in origional packages, unopened. One of them is a Lockheed P38J Lightening and has a number 7 on it. One is a F-47D Thunderbolt with a number 5 on it. One is a Focke Wulf 190 A-4 with a number 1 on the package. There is no manufacturer name on them, no scanner bars. Does not say if made in USA or anywhere on package. There is only a picture of the airplane it is modeled after on the front with a "bulls eye" and a propeller in the middle, and it says "fly with Power Prop Flying Gliders. The packages appear to be aged. I would deeply appreciate any info on these anyone has to offer. I bought them purely because I love aviation and they were unusual.
