Tank ID help

I think due to the size of the tank it would be a rather silly pony. I'm not sure it worth getting hydro and viz for the tank considering how much use I would give it. Selling it does seem like the logical choice

The 1800s are a little unusual because they have an inverted bottom, at least from the photos. I do have an LP53 but it has a standard shape. I don't find it to be very useful.

Smaller women can use the 50s if they weigh less than an 80. They consume less air and the 50s can last as long as an 80 lasts a guy at the same depth.
