This is a Siemens pyramid model with the more elegant thinner bell set. This telephone has been stripped down and rebuilt after each part has been cleaned and polished. The bell set contains double gongs producing a beautiful ring tone. The handset is marked Siemens and the cradle is the early model. Siemens made telephones for export all over the world. It is fitted with a best quality hand plaited GPO style braided handset cord, an electronic microphone and a GPO specification round plastic line in with a UK plug socket. It has the earlier GPO No10 dial with a number only enamel face. This telephone has been totally rewired and fitted with a pulse to tone unit to enable it to work on any network and also VOIP. It has been tested on our own BT land line and Grandstream HT802 ATA with Sipgate and is fully working to simply plug in and go. See video below. I love these Siemens models but they are getting few and far between these days. I can make a dial label with your information at no extra charge.
