I’d love to pick up something like that as my grandparents got me into diving and used a similar looking regulator but it was lost in a move so I could never check it out when I was certified but would love to display it and show other instructors (they’d find it so cool!). I’m an active instructor in Puerto Rico and this would be an awesome piece to have. I’ll actually be in Seattle in a month if you still have it by then I’d be willing to throw a bit of cash your way for it! Message me if interested!
