Hi. Does anyone know wot brand the electric aerials are that
are in VB VC VH SLE's as well as WB statesman. (The bullet tip aerial)
And where can I get a new mast.

I've never had a brand label remain on a VH SL/E aerial, as they didn't have the splash guards to protect them like later commodores. They are just a big, chunky, mud-encrusted box!

From wrecking out a few Calais over the years, I've found early VK had a Philips brand aerial, which appears to be physically identical in the housing & motor design to the regular VC/VH SL/E ones - it is a big rectangular box type housing, with a cylindrical motor mounted vertically on it, with the whole housing being a yellow-zinc plated finish. It is slightly different to the VH electrically - the Philips VK one operates like the later Eurovox ones, as Rhys mentioned. These were also in Camira SL/Es from the era - just the escutcheon for the guard is different.

VL eurovox (and later VK) are a far superior aerial, but are hard to find. They are much more compact than the early type - a small plastic "pancake" type gearbox housing, with a round yellow-zinc cover on it, and with a flattened cylindrical motor (like the shape of the bosch power window motors in the VH).

While VL are hard to find, VN-VS, or VT-VZ eurovox aerials are far more readily available.
There are slight differences in the top nut & mast diameter between VN-VS & VT-VZ - hence why I have listed the types seperately. Both types can still be used as a retro-fit, but VN-VS fits better.
These VN-VZ Eurovox ones are the same in the body, and electrically, as a VL one, but the mast has a black plastic barrel tip, not a metal one. All the replacement masts (Aerpro AP250) have plastic tips as well.
