Question for the 75 Series Experts

[Jason Edge]

I posted this on the 75 Series forum trying to help a contact and thought I would throw it out here also:

On the Body Name Plate on the 75 series I have pulled in over the years, following the word BODY is always the initials DC.  ON 62 & 63 series for the 1963's and 1964's I deal with it is[b] FW [/b]which I understood to mean it was assembled at Fisher Body's Fleetwood Plant.   

In the book "Cadillac Fleetwood Series Seventy – Five Limousines 1937 – 1987" it says on page 5: “ Starting in 1956, Fleetwood Seventy-Five bodies were handcrafted by the skilled artisans at GM’s Plant 21 in downtown Detroit then transported in special closed trailers to the Clark Avenue plant across town.”  There is a paragraph about the and production and production #’s (6 to 12 a day), but ends by saying “ The last Series Seventy-Five bodies left Plant 21 in mid-1984”.

So DC ultimately means Plant 21,  but I have forgotten what the initials DC stand for?  I think I knew it at some point but the grey matter is not retrieving it right now!   Who knows why DC was used as the designation for these 75 series?
thanks, Jason.
