This is a very rare field trial 712 Trimphone. These were issued to employees to assess the telephone before production for the public. As you can imagine they are not a common item. I have had them in two tone white, two tone Green and I even had a clear one. I have yet to find a blue one but am sure they were made. This one is wired up and actually works including the sounder which usually fails. I have not fitted an electronic microphone in it because it is a collector’s item. This is in almost perfect condition and the only thing I can find is a small nick in the curly handset cords which has been either painted or nail varnished. Not a real problem because you could fit another but I wanted to keep it as original as possible. The line in cord was not with it and so I have fitted an original 722 version with the curly section and fitted a PSTN plug the end.
