Yes Maurice, thanks for reminding me. Some years ago I acquired it on vhs. It is on a collection of vhs tapes obtained at a Group 9.5 gathering made by two late members John Stocks and Ken Wordsworth. They had both made tapes of sample of various colour processes. These also include Freise Greens “ Song of the Road” the German “ Munchausen” 1943, as well as samples of Gaspar, 2 and 3 colour Technicolour, and various other colour stocks available from different film manufacturers for us amateurs.Ken Finch.😊

Apologies for going off topic a bit but have just remembered that “Seven Brides for Seven Brothers” was Ansco colour, but I think this was another subtractive process. Ken Finch😏

Ansco Color was marketed in North America, actually, it was Agfacolor.
