Automatic Keying Device Type 1

A very nice mechanical device.
The Morse code can be set on the left (about 25 characters)
Interval setting can be made on the right (between 15 and 240 seconds)

All mechanical, output is only a switch (key) contact which will go to an transmitter.

Where would this be used? Beacon, Airfield ID, or.....???

Any idea?

Air Ministry, Loading unit Aerial type 111
Sure for ground use, only used with..........

Time Base unit Type 121
This unit started life as a BC-929 (APN-2), but was heavily modified !
And NO, it's NOT a HAM modification, see the ID plate! I also have seen a second one!
Previous owner thought it could be part (or used with) talking Rebecca.......

Yes, the connectors are now laying loose, but they should be there! (as seen on the other unit)
