Yep. Cadet Squadron 19 had different symbols. I think it was first Playboy 19, then in the mid 70s they got the right to use Starship 19 from Gene Roddenberry, then in 1992 they became Wolverine 19. It looks like in 2023 they went back to Starship 19.

19 has historically been a relaxed squadron (doesn't beat on their freshmen) and it has also been called "Recline 19". Not like Mach One or Tiger Ten where they have a more harsh approach to freshman.
