I have seen two different labels that came on those blue plastic cans. One had a picture of diver and the other was a split Voit/Blue 50 Fathom. Don’t know if that tells you what’s inside.
I believe the silver label with blue graphics was the older one: this is only a guess so please don't take this as what's for sure true. This is what mine came with, I'm not at all a Voit guy, I just got it for cheap and then found out that it was really rare. The original labels were a water-proofed paper, not plastic/vinyl. I think both types of valve bodies had the silver with blue graphics?!?!?!?
