Sooo, finally… Finally I was able to add a transparent model to my collection. It was not easy but sometimes you are just lucky.
There was a chance to purchase a clear model for me earlier this month. It is in very good shape, with only small damage on the back and dial face. But for the rest the shell is very well preserved. It has a flat earpiece and dates from 1963 (microphone date). The chassis is a K7 from 1961. As you can see, there are totally no secrets here, it is also equipped with an Ericotone 2 in the neck. And fully functioning!
When it arrived it was dusty and smudgy. Luckily the earpiece was not attached so I good give the shell a good cleansing on the inside and outside. The inside tends to yellow a bit overtime as I noticed but I was surprised that a bit of soapy water could do miracles here. I looove the dial face as well. A pity about the small crack (people will never learn…), but it is really cool.
The clear Ericofon seemed to be used as a presentation model to executives and commercial relations. Meaning it was actually never for sale. How many were produced is unknown. They seem to be available in all 4 case types although I have never seen an old case myself.
