Description
Natural brass.
Brass except steel spring and steel firing pin.
The fuze is screwed into the nose of the bomb and tightened with a spanner wrench.
A primer sets off a delay element which fires a gaine which in turn sets off the booster.
The upper portion of the fuze body houses the arming vane assembly. The lower portion of the fuze body houses the firing pin which is attached to a plug, and the two safety plungers which protrude beyond the point of the firing pin. The vanes are riveted to a sleeve which is screwed to the arming spindle. The vanes are free to rotate, but two grub screws prevent their falling off. A spring keeps the firing pin away from the primer, after the fuze is armed, until impact with the target. A selector unit permits a delay to be set. The standard Army gaine is surrounded by a booster. Spanner holes are present. A U-shaped safety wire is also probably used.
