.50 BMG identity

This .50 BMG blank was recovered from a British military range.

Although headstamped “ME”, is it made by MEN, as we are currently buying 7.62mm from them (L57A1 ball)?

Also very unusual to have “BLANK” in the headstamp.

Are the 7.62mm also marked “ME”?

Tony, this blank was made by Igman in Bosnia and Herzegovina for Manroy Engineering Ltd., which is currently offering these cartridges for their L9A1 blank firing conversion.

Fede, thanks a lot!

Many thanks Fede.

No, they are marked “MEN 09 L57A1 (+)”
