Don’t know if you are still looking, but I have a steel hp 119, 9/06 manufacture, current hydro until 7/17. Has a convertible din/yoke, full of air, needs a visual next refill. This is the 8X 8" diameter tank. Lots of air in this thing. I’m looking for something a bit lighter. Maybe a 100 or 80 steel hp. Swap or take $225 for it.
