I picked up three brass reloadable Leica cassettes on the weekend at a camera swap in Seattle. It seems that one actually has exposed film in it (I'll confirm in the darkoom). The cannister is labelled in pencil: Pan X, 40 ASA, April 1960. Can anyone suggest development times? I have Rodinal, HC-110 and D-76 on hand. Also, anything else I should do during the processing that I might not normally do? I'll make a point of posting any interesting images that I find. thanks!
