I cant be absolutely sure, but I believe this item originates from the 1930’s
A small sweet tin, the body of which is made from card board with the turret and track panels in tin plate.
The track panels are detachable, sugesting these are the lids, the turret seems immobile.
British maker details to the reverse.
Some rust staining to one side panels printed paint detail, and minor surface rusting to both inner side panels.
A ‘lovely’ item typical of a bygone age in child’s toys and confectionary.
