These parts are from a very early Siemens pyramid model. I would think 1931 and so as early as you will find for this colour. I have these sitting on a shelf in my work rooms for over twenty years. I have had the handset resin repaired as the metal insert in the hand grip on the mouthpiece side had cracked around the rim. I have never found a telephone to fit them on and so maybe a top class collector may have these parts missing. The body has been modified in its lifetime and looks to have been done in a house as it is very professionally done. Note the metal insert in the body. I have only seen this on very early black models from 1929-30. They all came from a complete phone but the base and internals have gone missing over the years. The handset has crazing and looks more like it is made from bone in colour. The body also has a crack under the dial.
