To me the 2 cylinders on the left side look like LP120, and the 2 on the right are HP120. I see a difference in cylinder diameters between the cylinders on the left, and the cylinders on the right. The 2 back cylinders might be HP80s, or like someone else said LP66 (I never seen those tanks before). I say HP120 because faber 7.25" boots are about 5" or 6" tall.
I noticed the diameter difference too. The back ones are clearly Scubapro branded Fabers, which makes lp 80 or lp95 likely, and the size and shape makes me think they're 95's. I can't tell what the graphics are on the bigger ones to even figure out if they're scubapro fabers or not, but they looked like something 100 or bigger to me.
