what is this car?

Looks like the Brit car the snotty Professor in the film "Back to School" drove (sans wire-wheels). I thought that was a Morgan, but a google says a 1945-50 MG TC Midget. Perhaps the Morgan was related since some Brit cars then were incetuous. If interested, I recall a Wheeler-Dealers episode restored a Morgan. MG TC in "Back to School"
Morgan is/was a separate manufacturer from Morris Garages, Triumph, Austin, et al. Initially Morgan started as a three wheel automobile. It had two front wheels and one rear. It used an air cooled V twin mounted between the front wheels with its crankshaft longitudinal. The frames were made of oak. The first four wheel motorcars still had oak frames. I do not know what four banger was sourced for use in the +4. Eventually they negotiated purchase of the Buick/Olds designed Aluminium 3.5L V8 for the +8 model. By this time they had steel frames. I may be wrong but I think Morgan may still be in limited production. The Rover V8 is out of production now. Rover has used Ford and BMW engines since.
