The Heemaf type 1931 is the very first telephone that was manufactured on an industrial scale. It is an almost exact copy of the Siemens & Halske modell 1928. In fact, Siemens supplied a lot of the parts to Heemaf, such as the dial and handset.

Heemaf started producing these, at the request of the Rijks telefoondienst. This model was also produced for the Amterdam citye telephone company, Plaatselijk Telefoondienst Amsterdam.

Until 1934 Heemaf only made desk telephones. To meet the demand for wall telephones, they developed a special wall bracket for mounting the desk telephone to a wall. This bracket is now a very rare item and very sought after by collectors.

  1. I have the Philips supplied one (like on this post https://www.matilo.eu/3-the-phones/1945-1960-late-bakelietperiode/heemaf-philips-telecommunicatie-industrie/?lang=en), it seems the handset is different.. the 1931 one looks slimmer.

    Is this the kind of phone that prevents the dial to be rotated when the handset is on the cradle? I’ve seen one somewhere on the internet..
    However in my phone the clapper will move and make a ringing sound if I rotate the dial when the handset is on the cradle.. is this normal? Or was a dial lock installed in my phone but it was broken?
    What is the behavior in your Heemaf Philips?
