Curious find from the park

HI all,went detecting at the park today,found the usuall coins,pennys and modern coins,one silver,sterling ring,and a unusuall bronze casting of a maori head.highly detailed,even has the face tattooed.not sure what this could have been,i,m tipping a old coin money box,as it looks like it has a second part to it somewhere,or clips together,any info on this item would be appreciated.take care and happy hunting.


Back of the Maori head has brooch pin fastenings, hinge at bottom and retainer (missing) at top

Same series as this 1968 bottle opener


Hi mudwiggle,well that solves that mystery,thanks so much for the info and id,i,m now much the wiser.
