I got this roll of film off ebay for cheap, Imperiale "S" Pan 400, Made In Spain. There was no box, it just came in the wrapper/film holder thing (1st photo). Anybody know who made the film? The only companies I know who where in Spain where Valca & Negra (found that info on a post here on the forums somewhere)
Valca used amongst other cassettes a very peculiar cassette, that resembles yours, but nonetheless is different in one detail, as far as I can see at your photos, which are unsharp.
