Technical 1953 Oldsmobile dual inlet aircleaner

I am installing a 1953 Oldsmobile 303 engine in my 1939 Ford Deluxe Coupe . I plan on using an original Oldsmobile 4bbl aircleaner . When I found the dual inlet aircleaner it was primered and I want to paint it in the original color but I don't know what that was , any help appreciated !

 

Satin black, I think. All the stock ones that I've had were.

 

Thank you for that great photo , black it is !

 

Thanks for that
