Old Pathescope movie from 1934, entitled Secret Of The Loch, on 3 reels of 9.5 mm film.
I've done some swatting up and its very interesting really.
It was the 1st film ever made about the Loch Ness monster.
It starred Seymour Hicks, Nancy O'Neil and Fred Peisley.
Directed by Milton Rosmer and edited by the late great David Lean.
At the time it was descibed by critics as " fairly amusing British monster movie " and by Britmovie as " an enjoyable comic romp ", I love that bit, very British.
Hopefully it plays ok, cant smell any vinegary smells anyway, so not deteriorated.
This is the silent version
