for those who remember what they are: Does anyone know what the various annotations refer to on Kodachrome slides?
Generally Ektachrome do date their slides but Kodachrome ones are hit and miss.
These are paper mounts and say eg 'Jan 8 M7' probably mid 1980's - Defenitely nothing after the 8 - maybe the printer had a bad day .
Others are clear 'Feb82 M6' which makes me wonder about the missing digit.
Kodak had a brief period with white plastic mounts and not a mark in sight which was helpful. Other times on plastic mounts it just had month stamped - no year.
Does the M7, M6? etc indicate naything useful?
Not sure where to post this so gave this area whirl.
