British 2 inch mortar round most likely a parachute flare one from the color of it
H Kradman! What exactly is a parachute flare?
It's a slowly descending flare used to light up a night battle , often seen in Vietnam war movies like Platoon , Apocalypse Now .
Cheers Chris! Never too old to learn hey ;-)
Its a illuminating round
I would also saw it was a white flare , denoted by the white exterior to the round . Nope your never too Old to learn something New !
Here are some photos of a post war one i have the same , may help to show you the markings yours would have had
Geez Kradman thanks so much for sharing!
