Ahhhhhh......the artist knew his stuff. It's in the small details.
MG sold the TA & TB roadsters before the war, the TC arriving after. The three variants are pretty much the same car, simply with mild developments incorporated. At a glance, a TA, TB, and TC will appear identical.
One quick way to discern pre-war from post-war is to check the number of trim strips on the running boards.
TA & TB had three per side, and TC had only two.
It's diddly little trivia.....but it appears that the artist above....got it.
I'll add one more bit for the car/avian enthusiasts.:
There is a folk legend that persists about a race between a Red Label Bentley and an MG that took place from the coast to Paris, once that city had been liberated.
An old friend, now long deceased, was a doctor attached to the RCAF. He'd have been the one you'd see at the end of the runway sitting in an ambulance with an orderly as the bombers departed and returned
His name was Dr.Jim Waddell, originally from Calgary, and I knew his as a life long MG'iste in Victoria, BC.
He claimed the race really happened, but sadly, while the folklore gives victory to the underdog & tiny MG, it was in fact, the Bentley muscle car that carried the day. Of course, he was in the MG, and it was all airforce people, and it was all just a big party.
Appologies for the diversion....MG's get me going.
Please now....back the N3N. (Yet another type of open air roadster.)
