As a fifty year old guy who has studied ww2 planes all his life, to me, it doesnt fit any "real" plane, but more of a generic "warplane".It does slightly resemble an SBD dauntless, because of the bent wings, but my first impression was more of say a p-36 hawk, the predeccessor to the p-40. The dauntless and devastator had squared noses , and the canopies are wrong for any type of "real" plane, but being as it was a toy,some variations occured,because it had to be toughly made.Is it pressed tin, or steel? If it isn't a copy, I would date it to around 1936 to 1945. The markings are correct for up until 1942, as another poster mentioned.Does it look like it may have had a nose part (cowling) that is missing? Very cool little plane, in any case !
