Mystery Ammo Fuses/ Pimers WWII Australian Military Commonwealth Issue?

[AT P Sweep]

Hey blokes

Seems we have had a run on mystery primers and cases etc in our archeological and Metal detecting WWII sites here in Australia ~

Ed my off sider found six of the larger primers / fuzes which we had not seen before ~

Ironically I found a same similar also but mine was smaller but with no inscriptions ~

Any advice appreciated ~
