This is a bit of a weirdo bid, seems to be hammerited blue and has a morse key.
It runs off 2 x 3V batteries, will let you know when it arrives.

The bidding went high, so I forgot about it, then found out I was the winner...

That is so cool. I hope you have brushed up on your code.
I can do S-O-S, maybe I should contact my bank and use the morse key? ;)
Funny what you find on a Google search, it appears this model was in use as early as WW2, I wonder how old this one actually is?

There is an exhaustive history here in a PDF file:

Amazing amount of information, BTW makes sense I won this my late dad was Royal Signals Corps 1953 to 1956, he probably used tons of these!
You might try checking "Fuller phone". My spelling may be off.
A fuller phone was a code key and i beleive a handset. I had 1 long ago.

Jim, brought up this:

Do these really work off a one-core cable?
Amazing.
These works, and they make you deaf!
The buzzer or howler makes both end receivers howl loud when pressing the key.
It will work together with an ordinary fieldtelephone as EE-8 or FF33.
Depending on grounding, and noise it may work quite well on a single wire, and ground return.
This howling system was used on early telephones due to low cost compaired to a generator, and for morse signalling on bad lines. The latest I know who had this as a military telephone is the Swedish "Fältapa" M37 (Fältapa is Swedish shortform for field apparatus, but apa may very well be equal to monkey ;D)

Thanks for the warning dsk, maybe get some earplugs before I fire it up!
