I agree, the rudder looks like a Ju-52.
The USAAF wing is most likely from a B-25 with the somewhat non-traditional insignia on the upper right wing. (Typically US insignia was placed on the upper left wing and lower right wing.) The small "V" cutout at the far right lead edge is for the landing light.
