Ryton Assembly Plant in Coventry since Arrow production moved to Linwood, Scotland in 1969, this photo I believe was taken in 1967.
Lets start from front: The left-hand-drive red Sunbeam I believe is a Sunbeam Hunter which was for the European market (it could also be a Sunbeam Arrow which was for the North American market, but I doubt it). Behind it are bunch of right-hand-drive models, this is very interesting, they were building LHD & RHD models on the same line. In the background there is a brownish Humber Sceptre, and bunch of Wagons. Oh boy this place was on fire! ;)
