Trying to find early 1970s Viv Neves film

[knocker]

There was a film starring Viv Neves that came out about 1970.
As far as I recall it was known as "They died with their boots on" but it is also referred to as "Whirlpool".
Anybody got a copy,or knows where it can be found?

Thanks in advance

The film was "She died with her boots on" aka "Whirlpool" which was reviewed in magazine I have from the early 1970's called "Porno Screw Colour" - I suspect sold mainly for its title as it didn't contain porno or have any screwing and was only partly in colour.
I've Googled a link, for what elsewhere is described as very rare, of what I suspect is a copy on DVD-R at $14.95 .
