I was at a local business today when I noted two scuba tanks sitting outside next to a door. Note that the weather today was extrememly cold and last night wa freezing rain, so I thought that a little odd. I asked inside and the owner said that they were left behind in a house he bought by a person that got out of scuba diving a long time ago. He said I could have them free and I could give him something later if they turned out to be worth something.
They both seem to be steel, and one seems to be galvanized and painted, I would guess they are somewhere in the 60-70 range since they don't look as big as an aluminum 80 that I am used to but then its been months since I was diving and I didnt have that much experience so I really dunno. They are about 22" around and about 25" tall not including the narrowest part of the neck and the valve. weight is about 28.5 lbs each.
Now the bad parts, the first thing I did was crack the valves open to see if they had any pressure in them only to find that they had been sitting with the valves halfway open, I don't know for how long or how long they were outside.
I decided they couldn't get any worse from my meddling and took both tank valves off to look inside, both came off really easy. One was a J? valve (the one with the reserve handle) the other was the K valve, the k valve has a chip in the mating surface inside the o ring that I will have to have looked at to see if its even rebuildable. Last VIP date on both tanks is 1992. I just hammered the boots of of both tanks, the yellow one has flaky rust under there, the black one was unpainted under it and had a white chalky material, definetely galvanized.
Tank one has the older valve and is a yellow US DIVERS CO aqua-lung it has light surface rust on the interior in places, but it seems to be something that could be removed I think if I put it in a machine to turn ammo casings and filled it with the abrasive stuff for that. I question whether this tank is useable with that rust. It has the following stamped on it:
1CC3AA2250
K44880
USD
2067+
4 vsd 76+
3 B3/02 89+
Tank 2 is the unidentified black painted tank that appears to be galvanized, the interior has only a very faint rusty color in spots (no texture to them) and would clean easily. It has the newer valve that may be junk due to that minor damage.
DOT 3AA2250
HJ426487
<0> 6<0> 78+ L (in a circle or a C, not sure which and I dunno what the funny symbols that look like zeroes with ears are)
also stamped cruedely by hand on that tank is 2sd83
Am I correct in assuming the older yellow USD tank is a living room ornament and the newer galvanized black one may be saved depending on the VIP and hydro results?
What size are they?
EDIT: diameter is 7 inches, do you measure height just to the point where it starts to narrow, or up to the base of the neck? These seem to be steel 72-85 or something.
