RTT 72 from Belgium

Purchased this phone off ebay last week and received it two days ago. These are the photos as I received it. It only needs just a clean and polish which will be an easy restoration for me. Everything is intact and just a few light scratches. At first, I thought the dial center was missing, but found out it was still intact, minus the dial card.

Isn't the logo just "RTT" for Regie der Telegraaf en Telefoon/Regie de Telegraphe et Telephone?

Anyway, thanks for showing and congrats for a purchase in good condition. It's time to care for this and other types of "grey mice". Soon they might be rarer than bakelite or the hard-to-avoid kettle phones.

If you have info, like wiring diagrams, production dates,... please add! There seems to be nothing on the web about this phone.

Agree that it's an RTT logo. Looks like it's made by ATEA from the bell coil. Still using an AE pattern dial too.
I must admit I tend to pass over phones like this as a bit too modern for me, but I may need to reconsider as I agree with @countryman that they could soon be rare things.

Mine looks very similar, but the bottom piece is a dark ivory color and stamped "RTT 72 B" on the bottom. The piece which activates the hook switch on mine is clear plastic, not metal. I am guessing that mine is probably slightly newer.

Looks like the dial off normal springs are shorted at the connections.

Is this what you are referring to, the possible short?

Yes, that's it. It may not be at the moment but it looks like it is busting to.

Thanks for pointing that out! I probably wouldn't have noticed until I tested the phone.

Here is also a picture of the wiring diagram. I will later post a scanned version for the wiring diagram thread.

Interesting that there is no automatic line length compensation.
