In the collection I have this Sahara flat model from 1967 that is in perfect state. There is however something with the color code that I have never seen before. But then, I haven’t seen more than approximately 350 Ericofons from the inside sofar.
The colorcode inside the phone is wronlgy indicating a ‘Crystal Mint’ color with code 520552. It should be 520538 instead which is Sahara. Never seen these kind of misprints before. If you have more examples please share them with me.
