My dive shop begged me to take this old tank for free because it wasn’t something they wanted around so I took it.
I “think” it’s an old CO2 tank converted into a scuba tank.
It’s a little shorter than a 72 but appears to be about the same diameter. The markings are:
ICC-3AA1800 (?) the 1800 is not very clear but I suspect that’s what it is. Following is another number F470498 (serial number?)
Then “C-O-TWO FF CO” below that.
It has an insert sleeve to convert 1” down to 1/2” tpt
and the bottom has 6 bumps around the perimeter so the tank will stand up without a boot.
What should I do with it?
make a bell, or is it worth hydroing?
