Mega Rare version of the 1960's Control Tower - fitted with a battery powered circuit board and loudspeaker to allow the user to 'broadcast' announcements to the circuit via. the hardwired mouthpiece.
A great fun feature for children of the time !
Untested by me but I have no reason to doubt it wouldn't work if connected with the right battery.
All lugs to the loudspeakers are fully intact , comes with an original uncut flag sheet.
rarely available - don't miss the chance to add to your collection.
