I believe this is called a bat winged air cleaner. It looks like its for a 4 bbl and is also an oil bath system. I got this years ago in a parts collection and don't know for sure what years the application is correct for. A previous owner repainted the exterior, but didn't refinish the interior parts. Price is $200 $150 plus shipping from Southern Oregon. Check out the photos and contact me with any questions. John

 

According to the Olds parts book these were used from 1952 thru 1956 on four-barrel carbs.

 

Thank you Charlie!

 

Cadillac also used these while Buick and Pontiac did not. My 54 Olds had one and I took the oil bath out and put a dry paper filter in. I still have one of these. It fits the old 4GC carb and will not fit a Qjet although it could be modified. These were very popular with hot rodders back in the day.

 

Well, I checked ebay and found one for a Cadillac at $179, so my $200 was too high. Price reduced to $150 plus shipping from Medford Oregon. John
