Great find, thanks, Tom.
I put in my home town "Plymouth" and up came several films. The one I enjoyed most was the return of HMS Amethyst - mainly because as a schoolboy my mother took me to "Rusty Anchor" in Plymouth to see the ship crossing Plymouth Sound. I also remember the ship's cat "Simon".
Later I watched "Amethyst" being broken up and scrounged a length of her mahogany.
