Question Help with Capacity on this old Faber/Scuba Pro Steel tank.

[lnjohn]

Trying to figure out what I have here. I always thought it was a 50 or 57, but after noticing that this tank is steel with a 3000 psi, I think it may be a 72. Any help is appreciated
readings as follows:
Faber/Italy Scubapro
DOT -3AA-3000-92/9091 057 M8303
10/92 +
My research is saying Chromoly Steel working pressure 3000 psi, 10/92 is born date, started with a + overfill rating. I have a steel 72 as a point of reference. If this is a steel 72, anyone know bouyancy characteristics full and empty?

I've never seen a +-rated 3000 psi service pressure tank. So, 3300 fills if current? I have one of those (no plus), and we called it "medium pressure", and do 3000 psi fills. They are heavy tanks for their size....

those mid pressure fabers generally had the REE stamped on them, so applying the + rating is straightforward at hydro. they also only reached the stated capacity at the + pressure like LP tanks.

yours looks to be the fatter 95cf scubapro

Scubapro/Faber LP 75.8 Chromemoly Steel Tanks

I've been offered a Faber LP 75.8 along with this nifty catalog shot. I want to buy myself a tank but I'm a bit of an air hog so I was hoping to buy 80-104ish CF. How would this bad boy compare to an aluminum 80? Would I even notice the difference in capacity? How do they compare otherwise in...

This was very helpful, it is the shorty 71.4@3300 psi, recent hydro doesn't have the + rating so I am looking at a smaller than 72 tank, but it's bigger than I thought, this may be a good option for shallow beach dives. If my math is correct, this may be closer to a 65 @ 3000 psi, but size of a 50 aluminum tank, with better negative bouyancy.
