I suspect, but haven't been able to find photographic proof that the coach being "towed" by the Eagle is a 1980 Caravelle 22'. My theory is based upon the presumption that the 1980 Caravelles were based upon the 1977-79 Argosy Minuets whose production ceased in 1979. My notes indicate that the coaches had the narrow body of the Minuets and virtually identical floorplans (which the window arrangement on the coach in question seems to point toward). The photo that I have attached below is one of the 1977 6.7 Metre Argosy Minuet and was posted by Forums member Loudruff --
While not exactly identical in window arrangement I sense some similarity, and AMC products were often used in advertising the Minuet products such as the AMC Pacer with the 6.0 Metre Minuet in the scan below:
I have been able to locate photos of the 20' and 14' Caravelles, but not any of the 22' Caravelle.
