Tank ?

[fringefan]

I am not an expert on reading tank number so I need to know if I am correct thinking this tank is the following

1. Aluminum
2. 6498 is the type of Aluminum US Divers Aqua Lung so I am assuming it is a Catalina
3. Rated 2475 pressure

I don't know what the cubic size is so any info would be a big help.

3AL DOT-SP 6498-2475 Z1272 USD 172 1087 5 95

I know enough about the 6498 that it is not a concern

Thanks

Without seeing the tank I can't say for sure what you've got but I'll take a shot.
3AL = Aluminum.
No it's not Catalina. I believe it was called an aluminum 72 made by Luxfer
With a service pressure of 2475 it's probably taller than an 80 but smaller diameter
The 6498 is the Special Permit number.
Z1272 is the serial number
1 72 is the original hydro date. 10 87 and 5 95 are also hydro dates.

Okay so I was a little off and yes it is taller

Is the tank worth buying? I thought that all Us Divers Aqua lung tanks where catalina's but due to the age I am assuming that this tank is made of 6351 Alum. I have not heard of many people using alum72's, what are they mainly used for besides the obvious. Thanks

Yes its 6351 alum.

Its only worth anything if you have a shop capable of VIPing it properly and willing to fill it.

I beleive it's also what we used to call a "floater" -- it goes VERY positive when it's empty... A modern AL80 is bad enough...
