This was given to me by a friend, she said it had been sitting in her attic for decades. What is it? Cant seem to find any information online about it. Chemistry lovers, please help a curious mind figure this out.

Thank you so much

Looks like a gas scrubber. Gas goes in from the the top tube, bubbles through the solution and goes out through the side tube. We used similar (albeit smaller ones) to remove traces of oxygen from argon, used in turn to wash oxygen from the solution in electrochemistry experiments (oxygen almost always interferes).

Yep, that's the thing. Apparently "bubbler" is a better name.
