WW2 WS38 MTLL No.2 Mk II Throat Microphone ZA 19734

This wonderful looking historic device is a WW2 WS38 MTLL No.2 Mk II Throat Microphone ZA 19734.

In very good cosmetic condition with some surface scuffs and blemishes. It comprises two carbon microphones, which attach to a bakelite junction box before connecting the microphone to the Wireless set 38 and a set of headphones: the latter two items are not included. 

Sound was picked up & transmitted as vibrations through the carbon microphone worn just above the Adam's Apple. Air and tanks crews reported that voices could be heard better over background engine noise better than other types of microphones.

It is marked on the front centre metal label:-
Mic & Recr H/Gear No.5 Mk II ZA19605

and on the rear:-

MTLL No.2 Mk II  ZA 19734
