I'm going to risk something very obvious, but for something you have to start.
Piper J3 Cub
In order to be more precise we should have at least some amount of alar placed, or the confirmation that does not have them.
Air intakes on the hood and know if the 4 spots on the left side of the nose belong to the model or the table.
Could you put the wings, the engine and take the same picture again?
