Danny, the white canaries are a rare breed indeed, and only for you!
Oh yes, the antennae is another pointer. The wingtip wires are mercifully absent and thus avoid pilot entanglement.
Bernie, I think that the bulges that you refer to are the fairings of the main undercarriage. It seems that it was a peculiarly US arrangement whereby the gear retracted rearwards, rotating as it did so that the wheels lay flat in a bay behind in the wing under surface. It can be found on a number of other types, such as the P-40.
