And in a parallel duplication lots of AC Cobras and Shelby Cobras, with the occasional same car (from chassis no.) occuring on each side of the fence. Should we remove Shelby as a maker name for all Mustangs and Cobras, but have it in the model name as appropriate or if necessary agreed format? We may still need to recognise Shelby as a maker name for other
model/types, so it would not automatically disappear.

And before these discussions get too bogged down, sw68's original question still stands and can probably be decided fairly quickly. Not my specialist area at all, but I understood 350H was the official title at the time?
