Thanks Hanno

What stands out is the speaker . It is a speaker from the artillery battery telephone set , they had a speaker unit at each gun, the instructions came from the base unit . These speakers were carried two clipped together . I had quite a few of them plus the base unit . They were not meant to be used with a No. 11 set or any wireless set . The speaker had a button on top, you pressed the button and spoke back to the main unit , it was a two way setup.
