Nice collection of films there Panayotis, I did notice that on standard 8mm, in the early days, films were released more or less complete,
I stilll have Mountain's "Babes in Toyland", "Blood on His Lips" aka "Hideous Sun Demon", missing a rat eating scene that could be due to British censors at the time, otherwise complete, also "The Demon Doctor" reduced to 4x400 on s/8, but full length on std 8mm,5x400', as was " Retreat Hell" 5x400 std 8mm, cut to 4x400 S/8. Mountain were the worst at penny pinching at the cost to the customer, which is why I avoided their "sales"i n the '80s, cut to death film.
