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.
Thanks

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.
