Here's info off the car tags
It is a model K5114 (1951 Kaiser Special 2-door sedan).
Original color was Mariner Gray (375) with Explorer Gray Richmond Cloth upholstery
The car has factory-installed overdrive and was built originally for sale in the 48 United States rather than outside the USA
The Accessory Group (K-F's name for Preferred Equipment Group) consisted of directional signals and oil filter. NOTE: The filter on the car is a type 1/2, The replacement canister filter has been out of production for nearly 50 years and I would recommend replacement with the easier to work with replacement element filter unit.
The body is the 5,932nd 2-door special body built by K-F. The car itself came off the production line at Willow Run MI on the second working day of November 1950 (within 2 working days into the month).
