Flat hook/clip in white metal. These have two female press stud fasteners for attachment to an early type C, D, E or N helmet, thus allowing the use of a type E*, G or H mask. Also for use with modified type-B helmets. Correct wartime pattern and not the later postwar type used with the F & G-type helmets. Some tarnishing and wear but in very good used condition.
