Old Floor Jack I.D. Help

Any idea what I've got here? Gave $12.50 for it at auction.
Handles slightly bent but otherwise works great.
Saw another like it with Montgomery Wards tag, but tag is missing on this one.

Another view, from behind.

Another pic. What looks like a tag is from a rebuild shop. In business since 1997, so at least it's been apart within the last 20 years!

Thank you HiBall!
Any trouble areas I should inspect? Any idea how old?

Not really.. Lube all pivots, wheels and Use it, I don't know of any way to pinpoint a date on the WS, >50 years isn't out of the realm as they made them for quite a few years.
