hmmm - nice car. Pure conjecture of course, but I'm betting that's a late 1962 or early 1963 Humber Super Snipe Series IV. Inline L-head six, twin carbs, power steering, power brakes, two-speed Borg-Warner DG automatic transmission, full leather upholstery, wool carpet throughout, full walnut paneling, even a sliding choke control on the dash. Top rated speed 100mph, 44 BHP, high torque at low revs, brightwork across the bend of the boot lid, open/close rear quarter lights, front disk brakes, etc.
Just guessing of course. Jeez - who'd ever want one of those ...
Where'd you see it?
