I'm printing some B&W 35mm negatives for a friend, and I am curious to know what it is. She bought it in Roumania four years ago, and was told it was Pan-F, but the edge marking on one film is: "11 CBEMA.03.92", and the other is "5 CBEMA.05.91". The frame numbers are, for example, "10, 11, 12, 13", instead of "10, 10A, 11, 11A". The film is certainly fine grained, not unlike Pan-F.(posted 9231 days ago)My best guess, from the frame numbers, is that it is film stock. Any ideas?
