I am hoping to build the Spitfire Ib and IIb in 1:48 scale by changing the wings from Tamiya's Vb with those on their Spitfire I, plus switching the fabric-covered and metal ailerons, removing the spurious humps over the wheel wells, and using a spare rotol propeller for the IIb. I can also get a Spitfire Va by going the other way.
I am assuming that the lumps, bumps and bulges associated with the canon were the same on the Ib and IIb as they were on the Vb.
Am I correct?
Also, would the Va have had the early round exhausts, or the later fishtail type?
