Well i'm thinking my 1/72 P47, P40, and Corsair, they all match up in length except the P40 is a little smaller overall. Terry already helped me with the dimensions on the B17 (One day!!) and I dont plan on baseing anything else. Reason is I bought the sceneic cement and sprayer, soil, grass, rocks, and other stuff and really want to have fun with it but on a small scale where not too much can be lost if I mess up.
