Flat hook in white metal. Has twin female press stud fasteners for attaching it to an early type C, D or E 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 types used with the G-type helmets. Tiny stress fractures on the press stud sleeves (see pics) but these do not detract or affect the use of the hook. Very good used. Stock code H18319.
