Default No 150 candlestick questions

Bought 2 no 150 phones at auction today.
Can anyone tell me why the cutout on the receiver cap is there? (See pic)
I have 2 and same cut out on both although caps are slightly different, one stamped GEC, other just 2 C.
One of the receiver cases has gone a brown colour, any advice on getting it black again other than paint it.?
One has a no4 top that has been crossed out replaced with 150, other side AK22 with 236, other phone 150 PX25 234.
Both are marked CB on bracket. No4 dial plate in place.

The cut-out on the receiver cap is so that sound (especially the howler to alert the user to the 'phone having been left off-hook) can still be heard if the receiver is left earcap downwards on a flat surface.

As to returning browned-off ebonite to its original black, it is supposed to be possible, but I have always found that those who claim to achieve it are unwilling to share their secret.

Thank you, I learn something new here everyday be it telephony or radio.
Great idea, would have been left out these days as a cost saving measure, a great way to to tell if it's right for the model. Thanks Russell and Dave.

You are lucky to have found any with the ebonite intact. It is actually hard rubber and has usually broken off leaving the brass structure visible.

If you rub the ebonite with your hand to warm it a bit you will probably be able to smell a rubbery smell.

There is a picture of mine which is in pretty good original condition in post 12 in this thread https://www.vintage-radio.net/forum/...ht=candlestick

It's an antique, don't try to make it look like a replica!
