Two British No150 Candlesticks

[Jack Ryan]

Interesting. I am guessing the thumb size indentations on the end caps are for the same reason WE added bumps to their receiver end caps. It was to allow the sound of the howler to be heard if someone did not hang up and put the receiver down on the end.

Yes it is. I wonder though why it took WE another 30 or so years to do it?

Fourth and fifth photos are the '22' endcap which came on the Siemens Candlestick, and which needs replacing.

I think that's from a pair of headphones - does it have a howler groove?

Edit: I forgot to mention, I can see the molecular structure of those - thanks!

I found the older Siemens Brothers cap.

The logo is closer to the Siemens & Halske logo.

Photo attached. No howler groove.

Thanks for photos. I have dug a few endcaps out from my spares and started a new Endcap thread:
