The export version of the Industar-61 lens with a distance scale in feet is very rare.
I know of only a few examples:
I-61 #6591212 (1965)
I-61 #8519490 (1973)
I-61 #8697161 (1974)
I-61 #8715502 (1975)
I-61 #8864961 (1965)
Does anyone have this lens or camera with documentation?
I'd like to know which countries they were exported to?
