a. Description.
(1) Mine (fig. 1-16) is a flat, cylindrical, steel casing,
approximately 3-1/2 inches high and 13-1/4 inches in diame-
ter, similar externally to service mine M15 (except for
height). It differs chiefly in having one filler hole in the side
and perforations in top and around side secondary fuze well.
Mine may be boobytrapped by installation of one or two sec-
ondary fuzes, each consisting of practice antitank mine acti-
vator M1 and any regular-type firing device having 9/16-
inch threads. Although inert, mine has a smoke charge and
primer M45 in main fuze M604. Mine is issued empty with
arming plug M4 assembled, but without primary or second-
ary fuze. It may be loaded with sand or inert filler in the
field.

the pressure plate and the belleville spring of the fuze, which
