Bladder is bad.  Do Not Know what Model - see pictures.  As you probably know Zeagle is a modular system,  the inflatable wing bladder is bad - will need a new bladder,  this wing unit can be removed.  The tank harness is complete and ready for use.
Do not even know the size - should not matter unless you are small or very large.
Feels like a large.  Surplus from a local fire dept dive rescue team - probably fresh water use only.
Here is a great way to create your own custom rig CHEAP.

Look close at pictures.  Unit may be missing something.  If not clearly shown in a picture "it" is not included.  So the answer to all "does it have" questions will be "no".
No returns - shipping is too expensive for errors - ask any questions.  This is a great deal for the right diver - more are listed separate in my store.  Welcome to pick up in Orlando, FL.  Check it out before buy.
