Intercom from two phones

[jerrytug]

Won’t be binning them.

As others will know, you can make an attractive lamp out of an old vintage telephone

Or they’re quite sought after as just phones.

But besides from that, there must be a way to do it if existing products are on the market!

But a cheap pair of license-free PMR Walkie talkies, take out the innards. Glue the mics and speakers into the appropriate bits of the phone handsets. connect to the curly phone lead, then glue the radio innards in the phone base. Arrange a power supply to your taste. It would be fun to have an old landline phone which worked as a walkie talkie off an internal nicad or something, that would really confuse the millenials..
Cheap and quite easy, you may need to experiment with leaving them both on permanent send, or using the PTT buttons etc, and they have voice scramblers for those secret shed conversations

You may be able to get a pair of walkie-talkies and fit their microphones/earphones into the GPO handsets and hide the rest of the W/Ts in the body of the phone.

You beat me to it!

we have 4 walkie-talkies for around the property. I have one permanently in the man cave and it works well.

For your challenge I think you need a internal telephone network. Not sure how but we lived in a flat that had been converted from offices and it came with internal extensions that you could dial from other extensions eg dial 4199 for kitchen phone and it would connect internally. Not sure what's needed but could be worth looking into.

Army surplus field telephones? It used to be cheap to buy complete sets, reel of wire etc, and got the retro look..
My dad had one he brought back from the war, we used it to give each other electric shocks
very simple and reliable.

Just found plenty on ebay

I the UK there used to be a number you could ring that would give a test ring back. If you plugged both into the phone line you ring the number and wait for it to ring back, hopefully when it stops ringing it means someone has picked it up, you could then pick your end up and talk to them
