Wondering if anyone knows how to determine age of Winkler Stewart-Warner Corp Oil Furnace. Or at least when these were first available. Being told it is from the 20's but need to confirm that.
Moved to AOP Residential forum.

How many times must one fix something before it is fixed?
I don't think from the 20s but maybe. Before my time in the industry but made up the road so my old oil buddy had worked on some. I was thinking from the 50s or so.
