Air Cleaner - Unknown Engine Size/Vehicle

Anyone know what year(s) and engine(s) this air cleaner belongs to?

You don't provide enough info like what size is the opening, size of the snorkle. Better yet, you can look here and tell us : http://nicksgarage.com/aircleaner2.htm

Sure looks like an early to mid sixties Chevy air cleaner to me.

That would be my guess. That oval air inlet is the clue.

Yup, chevy.

Thank you very much! My father placed this in his attic for years (from house to house). I bet this has not been on an engine for over 40-years.

I'd hang it on the wall of my garage as a remembrance of my Dad were it mine.
