WW2 British MK IV SPECIAL T-MIC GSR Gas mask with filter. dated 4/41(16) (V6) -
WW2 British MK IV SPECIAL T-MIC GSR Gas mask with filter with the harness and filter also being dated 1941, size large, overall in very good condition, The Mk IV Special T-Mic was similar to the standard Mk IV. The T-Mic was developed to accommodate a radio microphone through the addition of a rubber boss. When not in use with a microphone, the mounting hole was plugged with a Bakelite cap held in place with a metal clip. The production of three different types of facepiece was not very satisfactory, so Porton Down began trials in 1934 to find a single replacement, which would eventually be released as the Mk V. Both the Special T and Special T-Mic were produced in far fewer numbers, therefore are slightly rarer than the standard Mk IV GSR. (please note all our gas masks are for display purposes only).
