Just to update everyone, I had the rolls of films examined and their content date and location have been identified. They are of the Australian and American war effort in Buna north of Australia in New Guinea 1942/1943 against the Japanese.
Six of the films are specific records detailing remains of the Japanese who perished in combat and also footage of those who did not perish being captured in conflict. The seventh roll half contains aerial surveillance of the location and ground filming of an airfield where there are stockpiles of bombs and other ammunition being transported by trucks to aircraft while the other half of the film is full of poor exposures of planes in they sky and bomb drops from the air though these unlike the rest of the films aren't exposed very well.
The films are prints onto nitrate stock and not the original film that had been shot in camera. More research is needed to determine if this footage belongs to any archive and what rights I have to display their content.
