Ok here is what I have it is a set of doubles lp 104's or 108's???? I dont know which it is but they just came back from hydro & vis & nitrox clean today. I got them in a package deal & I dont dive doubles so I am selling them. They have stainless steel bands, dive rite 300 bar din manifold & dive rite trans pac adapters. They are rust free & located in south west florida due to size I do not want to ship them but will meet anyone half way within reason. Born on dates for both tanks is 3/96 with a hydro in 02 & now in 11 same for both tanks. Ser# 1A18 557259 R & 1A81 548061 R They also have stainless hose clamps with D rings on each tank & are filled with air because I did not know what mix would be most used in these tanks. I am looking to get $525 OBO for the complete set I might consider splitting it up it the money was right Thanks for looking
