Great, and if yoou have a 600 ohms resistance between 4 and 5 on the induction coil you may us about any transmitter capsule that fits in the handset.
More easy than the more common W28 with a 200 ohms resistance and no 0.3 uF capacitor.

I really like this and I have never seen one of those before.
