German Concentration Camps Factual Survey

I've discovered with a shock that this unique and crucial video is no longer for sale (original price was £25, S/h copies sell for over £100) Hence my reason for posting this. This was made in 1945 so the full horror of the Final Solution had yet to be realised, also there was lingering antisemitism in Britain so the narration does not dwell on how Jews were singled out. There is no mention of gays or Roma/Sinti.
