Hi & welcome :) There are usually several old car radio specialists that advertise in the back of the various classic car mags, who would probably be able to help you.
Thanks to everyone for advice. I ended up looking on some American car websites in the UK (because of the 6v thang) and found Adrian James in Paulton. He takes period radios and converts the innards to FM with any necessary 6V to 12V inversion. I have gone for a blaupunkt radio that fits my PV blanking plate and that he will supply with an underbody ariel, input for Ipod and charger for same. Expensive though, and I'll let you know how it turns out. For information, his website is . Richard
