Age of Williamson furnace?

[wbernauer (Walter Bernauer, CMI®)]

Building center is not giving me any love. Any insight on the age with this serial number? It’s “1111” the furnace looks like it’s from the 60’s

Edit: Williamson 724-10 built from 1965 through 1970.

The US patent office has a record of 1966 if I read the form correct. Print was quite small.

Could make sense.

You guys are awesome. I know they went out of business mid 70’s.

1111

Maybe you found the first one ever produced?

it may have been the nicest, cleanest furnace of that age I’ve seen. Ran perfect in 90 degree heat. museum piece. It was nice.

museum piece. It was nice.

That’s a cool find. And it reminds us why age alone is not a defect.

There’s an inspector on another thread that would beg to differ!
