Pretty sure it's a lamp/lantern piece, but what part, kind/age?

Went out to a piece of city property next to a graveyard, may have been a park according to old maps. This was pretty shallow, nothing on the back but the edges are rolled over.
Managed to straighten it a bit and this is everything it says!

My guess is the top of a Sterno can.

Ooh ok, actually while following that idea I found something kinda similar. Obviously not the same, but maybe its a kerosene stove "dial"?
It also has arrows...
