Is your welder an old , round , R2D2 type?

They used the word "Knock-out" on nameplates of machines from the 1940s:

So if the welder has that word on the nameplate, it's probably from around that time.
Leblond Ltd owns the name now, but K.O. Lee is mostly known for their surface grinders:

If you're lucky, you might get a contact for a historian that has documents for the old company.
