WHAT SORT OF LANTERN IS THIS

CAN ANY ONE HELP TO IDENTIFY THIS LAMP, IT HAD A FRONT COVER WITH A SLIT IN IT AND AN OPENING AT THE SIDE TO LIGHT THE WICK. IT HAS THE REMNANTS OF A CANDLE AND WICK STILL IN IT. IT WAS DUG UP WHILE DOING GARDENING IN VICTORIA 40 YRS AGO. I THOUGHT IT MIGHT BE A COACH LAMP BUT I CANNOT SEE ANYTHING LIKE IT WHEN I DO A SEARCH.IT HAS NO BRAND NAME ON IT AND AT SOME TIME IT HAS BEEN PAINTED BLACK. mAY BE IT WAS FROM A TRAIN AS IT HAS A HANDLE AND A HOLE TO HOOK IT ONTO A WALL. THANKS FOR ANY INFORMATION.
