Its interesting to read comments on this film I veg tried to purchase this from BP Films but Im told its not available but maybe in the future I thought after all the comments read that there would be a market for selling this however there must be some problems .Reason for my interest I use to be a TV engineer in the 60's and watch all the trade test films then I suppose nostalgia brings me to want to watch it again after what 40 odd years.Good stuff.This film together with the BP 'Plastics'film is typical of the film presented for colour quality at the time I wonder if any one has a 16mm or VHS /dvd copy of this they know of for sale.Maybe I will have to wait until they are available on the open market.
