Which bladder is this one?

I recently received a hand-me-down Zeagle from a friend's dad. He has no idea which bladder this is. He thinks it's an old Concept bladder. I would like to find out the lift on this wing. Any help is appreciated.

That is a # 7318 bladder and has +/- 44 lbs of lift.

Cool, thanks for the fast reply. I can't find any spec on this. This bladder came with the Ranger harness, so I guess it's part of Ranger system. Can I dive double with this wing?

The bladder was made for single tank diving.
