Black bakelite/metal desk phone made by Heemaf type Norm 1952 (made under Siemens license).

Does anyone have a schematic/ wiring diagram for this phone?

Nice one!   I assume when you say HEEMAF, that this phone was in use in the Netherlands rather than in Germany?

If you can provide photos of the inside of the phone including its terminal strip(s), some of us might be able to guess what schematic(s) are relevant or potentially useful.

Yes, (of course) I do. I'll scan it and put it in the TCI Library.

The schematic can now be found here:

According to a technical announcement, dated May 1953, the circuit of the Heemaf  type 1953 is the same as the Ericsson type 1951.

The announcement mentions various other improvements.

I've added a bit of translation to the schematic.

Let me know if it needs clarification.

You are most welcome.

It was on the stack of 'to be scanned' anyway.

this thread is missing its picture.

When a picture in a forum post is linked by the author to a website outside the forum, and the that picture is taken down, the forum has no way of displaying the photo, and there is nothing that can be done to get it back.

Moral of the story is to upload photos explicitly to the forum and not have links to outside pictures.
