67 Eldorado Body plate interpretation

[K_Cassutt]

This is an exercise to understand my Caddy colors and options.

Body plate shows manufacturing the third week of April, 1967  (4C).

Interior code is 440.  This is a head scratcher.  1967 does not list 440 as an option.  1968 lists 440 as an option.  The color is "Covert".  (How poetic, an homage to the Cold War of the time?).

Paint code is 40-yes the car was white before painting pinecrest green.  Code is 40.

The roof. This is usually a single digit for color. Right, for my car it's 65  the string is 40-65. 
65 means Sandalwood (6), cloth (5)  or  dark brown (5)  vinyl (6). Best guess is the latter.

Anyone else have a funky body plate code? 

[Cadillac Fleetwood]

Interior code 440 for 1967 is described as "Covert Darien Cloth and Vinyl", and was one of the standard Eldorado interior selections.
The vinyl roof code, 65 is "Dark Brown Cross-Grain Vinyl".  If it is code 66, the color is "Sandalwood Cross-Grain Vinyl".

Paint code 40 is "Persian Ivory" which has a decidedly pale yellow tone, as opposed to color code 12, "Grecian White"  which was "whiter".

The lack of a "Y" on your body plate tells me that your car is not equipped with a 6-way seat, which was an available option at $83.15.

LOL on "covert".  Admittedly, that was a rather poor choice on Cadillac's part.  The term "covert" as they intended it (pronounced CUV-ert, with the accent on the first syllable) means the feathers or down of a bird on its wings and tail which smooth the flight surfaces. It is roughly synonymous with "plumage". 

In a somewhat attenuated vein, for hunting enthusiasts, covert is the vegetation or undergrowth in which game birds, such as grouse, pheasants, and partridge are often concealed.
