SABRE color question

Hi all, am I correct in assuming that the USAF Korea Sabres had the interior of the wheelwells and geardoors in green primer, same for the inside of the speedbrakes?

Thanx

It’s a museum piece, but it looks bare metal. And the Sabre at Thunder over Michigan this year had a light gray speed brake interior.
