Age of Bard furnace in crawl space

Can someone help me out on this one.
It is a Bard with serial number 133306.
Yes, i will be recommend evaluation. The Humidifier unit and cover is laying to the left of the unit. I would think it is okay to not have the humidifier hooked up but at least they should leave the cover on.
Appreciate the help.

Hmmm, wish I could help but I is stumped.

Anyone have the code for these things?

Bard’s been around since the early 1930s.

Were there any preprinted numbers or letter on the manufacturer plate. Those should also be written down if there were any.

You can contact Bard in Bryan OH at 419.636.1194.
