How is it that there's never been a Pitman type variant o' this that's turned up? I say this because {Images #1001467 & 1001468}'s type origin was Santa Maria, whilst {Images #3354735 & 3354736} has all the earmarks of a Terre Haute type job.
FYI the car on the cover is not a Jag-WAAR, as our US cousins call them, it’s a Daimler Sovereign sedan/saloon available with 2.8 or 4.2 litre straight six engines, or a 5.3 litre V12 engine. It’s hard to tell from the front view, but a 2-door pillarless Coupe was also available with the same engines as the sedan.
I checked the number plate, and that car is long gone (scrapped), and they were in essence ‘badge engineered’ Jaguars.
I used to own a ‘real’ Daimler many moons ago, before Jaguar bought Daimler.
