They aren't unheard of in North America but are much more common in Europe.
mgnostic,
Thanks for the reply. I measured and inspected the planes and here's what I've found.
The red and white airframe:
Wingspan: 19.5"
Length: 12"
Motor: OK Cub
The USAAF plane:
Wingspan: 23.75"
Length: 19/75"
Motor: Webra 1.5
Blue/Green:
Wingspan: 42"
Length: 31"
Motor: It looks like it says ORONE in raised letters in a vertical line. It also had the number 6730 stamped on the engine block which I assume is a SN.
These all belonged to the same person here in the Southeast. He was quite a collector and I have no idea where he sourced these. It would be interesting to find out their origin and if they're vintage, antique, or just something he put together with various parts.
