By H & S. Size 1. 1943 dated. Broad arrow marked. Very coarsely 'knitted' heavy string vest with wide knitted cotton shoulder straps. These were issued to some aircrews as an escape aid. If needed the vest could be unravelled and plaited to form a strong rope to aid escape. One assumes that for a decent length of rope the escaper would have to use a fellow prisoner's vest as well.... Very good condition. Label has faint manufacturer's details, war department broad arrow, size and date. Stock code E22366.
