1500: The casting looks as if it could have been a fragmentation sleeve
for an early stick grenade. The purpose may have been to use the head
of a grenade as a booby trap. The paddle would have been to secure the
grenade so a trip line would work.

A booby trap could reveal somebody sneaking up on your trench or kill an
attacker who jumped into a crater.
