British webbing Map case No.2 , W & G Ltd 1944
Technically not Pattern 1937 webbing, (I believe the No1 type was approved in 1940), This type No.2, is a variation of the original No.2 and dates from 1944.
They feature a celluloid window cover for the map and a brown pressed composite board of "Tufnol" (thank goodness they don’t make it anymore) and a few pockets for protractor and china pencils. Maker is "W & G Ltd 1944" (Waring & Gillow)
Period photo is of NZ Army officers on the Treasury Islands in 1944.
