I've wondered sometimes if they used the Argosy line to run through old stock from the Airstream line. If I remember correctly, the double-sided "G248" key on my Argosy water fill is on the Airstream spreadsheet for early 70s trailers and ended in '74, but it's used on my '75 Argosy and apparently not on your '74.
