I wouldn't know about that, though it seems rather unlikely that the (admittedly not exactly common but it did exist) positive earth 11AC alternator would have its diode pack the same way round as the negative earth version.

Yes, "vintage" strictly means pre 1930 but my issue was about what a vintage enthusiast
might have radio wise, not whether the radio came from a "vintage" car.
"ex 2 base" hasn't provided any further curiosity satiation, but I think he's been provided with suitable advice by now..... "If you can't just switch it over by design, look for a polarity inverter for the live feed to the radio"- that way the radio case can stay connected to the body of the car.
