The Dutch PTT sold 3 models of Ericofons during the late 1970’s and early 1980’s. If you are looking for these specific colors you can purchase them via this site. Just send me a message.
Unlike the official promo poster above, all three phones have the white PTT logo on the dial face. In 1978 the first dial faces were without PTT were produced, as of 1979 the text was added. They are not new, but used and have been cleaned and are in full working order. And they come with the curly black cord and the original PTT plug.
From time to time I have other colors as well, but this is totally at random. So if you are interested, drop me a message and let’s see what I have at that moment.
When you are in need of parts to restore your own Ericofon, I might be able to help you out as well. I certainly do not have a store but there are some spare parts available.
Also for special projects, like an exhibition, project or fair, I might be able to help out.
And of course any tips, questions or comments from your side would be more than welcome as well.
