                                           HISTORICAL NOTES:                                         


There were only three Imperials offered in 1940 and all were Crown models on a stretched wheelbase.  Only one custom bodied Imperial was produced by Derham on the Crown chassis and survives today at the Ford Museum in Dearborn, Michigan.  Derham also produced a one-off Crown Imperial Town limousine

Basic styling was similar to other Chryslers, with larger doors and sheet metal.  The Crown Imperials featured front fender parking lights and came only with conventional running boards.  In six passenger cars the front seat-back incorporated storage compartments and there were foot rest on the rear floor.  The eight passenger models had jump seats in place of storage compartments and no foot rests.  The limousine had a division window and could be ordered with leather upholstery in the driver's compartment. 


Fluid drive, automatic overdrive and vacuum operated power brakes continued to be standard equipment on this line.  Both low and high-compression versions of the Crown Imperial engine used aluminum cylinder heads. 


The serial numbers for the C-27 started at 7807401 and the engine numbers started at C27-1001 and ended at C27-1875.
