GENERAL: |
|
The M148 is the same as the AN-M103 nose bomb fuze except that the booster cup has been modified so as to have the contour of the standard Japanese Navy type gaine. The shape of the Japanese Navy gaine had to be retained in order that it would fit into the cavity in the nose of the bombs. In addition the threads on the fuze body have been modified to fit all Japanese Navy bombs. (Use 1.84 in. -10 Withworth thread) |
