Please contact the seller direct and ask him any questions.
Introduced in 1936, some survived in use to the 1980s. This one was refurbished in 1966. Heavy iron construction. No dial as it was designed for incoming calls only with an extension bell. It has a PST cord fitted, suitable for standard BT lines or Digital Voice as it has no dial. It is fitted with a modern microphone.
It weighs 23lbs so collection is preferred from Orpington, but could be shipped. Contact details are below.
Note this is not mine and all dealings will be with the seller. Only go ahead if you are satisfied to deal with the seller direct and with no guaranties whatsoever ever from me at all.
