Oldsmobile-88
Very well known Exeweb poster
HMS Affray was lost with 75 crew a year after that film was made in April 1951. The last loss of a British Submarine.Seeing this reminded me of the film Morning Departure starring John Mills and Dicky Attenborough .
It floundered in the English Channel. It took 2 months to locate due to the amount of wrecks from WW2. It was found about 20 miles north of Alderney.
