Description

Best viewed on a large monitor using the magnify image feature.
There is some discoloration and a few small spots of corrosion from their 50 years of contact with the cardboard box. It is cosmetic only. A brass brush of piece of emory paper will clean them right up.
There is some rust on the one pin that I seen will need cleaned up.
