Found a old Stream Air and a DA AquaMaster (black cans) but owner only wants to display these vintage regulators. The AquaMaster has the non mag indicator on the body. I'm not sure it is the original cans on this one.
Anyway here is what they look like now. Going to put hoses and mouthpiece on them so they can be displayed. I'd really like to rebuild the DA but LDS only wants them for show. Owner isn't a big vintage fan.
