I have a few NOS Trivia Whiz marquees, not sure if that is what you are looking for or not. Let me know if these are of any interest to you. I don't think I have an airwolf marquee though.
I need the one built by greyhound....video trivia....sorry
I measured the opening....7 1/2 by 23 1/2 .... I'm also in need of a top metal marquee bracket....same length.
