I still have a working Minolta 1 Degree Meter from 1968 which I use in landscape photography. The meter is off a bit and I found the lenses to be dirty. I could not find any instructions how to open this meter for cleaning and maintenance. Any help how to open the meter is very much appreciated. The meter is still a very nice device for zone metering and worked nearly 45 years for me.
Thanks and regards from Switzerland
