I always assumed that the D-Type was never a full production model. I know they made a few dozen of them, but assumed they were fairly coachbuilt one-offs. This picture sure seems to indicate otherwise.
The panels were supplied by Abbey Panels of Coventry and shipped over to the factory itself to be assembled in the factory alongside XK140s and MK VIII sedans. These shots are from late ’55/early ’56 shortly before the factory was nearly flattened by fire in 1957, so this is indeed a rare view of the Coventry facility.
Just look at them all. This could easily be described as a D-Type assembly line; albeit a non-mechanized one. Fantastic.
