<p>I have strips of developed negatives from 1989.<br>
Seeking person who can tell me exactly/precisely what the edge markings mean.<br>
I already know that letters are probably coating alley IDs, and numbers are batch or emulsion #s.<br>
Need to find out manufacturing date of film that corresponds to the batch/emulsion #s.<br>
Strip A: "G Y" "4 7 8" "Konica Color SR 100"<br>
Strip B: "V" "4 80" "Konica Color SR 100"</p>
