I show two experimental Australian 60mm mortar shells. Both are unfilled.
I can find no references to trials or use and they are only marked with an arrow.
The yellow band is possibly a Practice shell and is marked :
ME. 12/55 which is Maribyrnong Filling Factory, Victoria, Australia.
The HE body has a red and a yellow band and is marked:
Dimensions are : 58.5mm body diam. 60.0mm adaptor diameter.
295mm long overall. I put a 2" mortar cap on the tail so uses a similar igniter.
Maybe Australian trials to make a 60mm shell for M2 or M19 USA mortars ??
Any extra information is welcome. I have another which is inert weight filled with a yellow felt wad over the filler and same dummy fuze. Not stencilled.
