Just tripped over this photograph which some of you might like for reference.

Any idea where it came from, Norman?

I took the photograph in Holywood :-)

The light-alloy cased .280 rounds were made in various different colours.

Pleasingly the blue one was restored to shiny aluminium by the use of wire wool and a bead blaster :-)

Like this Tony?

Sorry about the overprint but it was originally sent to someone I did not entirely trust.

Very pretty!

Why does the end one have a different coloured base?

It appears to have been anodised before the extractor groove was turned.

The alloy 30mm ADEN cases are like this, but that is because the electrical firing circuit would not function properly if the case head was lacquered.

They never heard of conductive laquers?
