Some detective work required please! Fellow collector Andrew has these three SPV 104s in his collection. They are believed to be all original including the aerials, of which there appear to be three types.
The most common version is on the left, the other two appear to be rarer. If you look at the roof top plungers, they are bare metal which indicates all three SPVs are very early editions.
Does anybody have further examples of the less common aerials? Or who can shed a little more light this?
