I remember reading somewhere that all the Argosy 's were built in a plant in Versailles, Iowa.
I had always associated only the Versailles plant with Argosy production, but there is reason to speculate that something might have happend in the 1977/78 time frame. (??Could it be that the Minuet, and possibly more specifically the 6.0 Metre, was more popular than Airstream/Argosy anticipated resulting in a change during the time in question?? - - or possibly only during intial production of units with the aluminum composite floor??)
In reviewing the 1973, and 1975-79 Argosy literature that I have in my possession, the following address is quoted in all but the 1978 and 1979 literature:
60 Vista Drive
Versailles, Ohio 45380
In 1978, the above address is mentioned as well as:
15939 Piuma Avenue
Cerritos, California 90701
In 1979, the only address mentioned is:
Argosy by Airstream
107 Church Street
Jackson Center, Ohio 45354
Another interesting observation in reviewing the factory Argosy sales literature, prior to 1979 the literature makes clear that the owner can obtain service from Argosy dealers nationwide. In the 1979 literature, the owner is urged to obtain authorized service from any Airstream or Argosy dealer.
