What appears to be WW2 era model plane collection. The B-17 is a commercial product while the B-26 and OA-10 Catalina show evident hand carving, but could also be a store bought model. All of the planes are missing parts and could benefit for restoration.
Please see photos to see condition and included parts. I don't know what scale these are, the B-17 has 18 wingspan. The B-26 approximately 10 wingspan.
The OA-10 Catalina wingspan is approximately 11.
