Australian M 104 Nose Bomb Fuze.

[ron3350]

This is an almost mint bomb nose fuze M104 SI AUST 12/43 made by Duly & Hansford in Marrickville Sydney, Australia. ( Made nut, bolts, spanners).
It has the D&H in a triangle monogram and was never filled.
The slotted wooden disc is at the nose and a black bakelite cap is on the bottom.

I ask if the AUST and SI means it differs from any USA or UK versions ? What does SI mean ?
