“Antique furnace”.
Hee! Hee! Is it a coal-fired furnace like the one in “A Christmas Story” that little Ralphie’s father had to do battle with on a regular basis?
You know you’re looking at an old building when you catch sight of the tell-tale coal chute on the side facing the alleyway.
exactly like that!
Except mine had a natural gas conversion burner retrofitted into it sometime in the 1950s. I do have a coal chute but the cast iron door has been removed and replaced with a glass window.
