 Looking for a pony valve

I wanted to make a pony tank from an O2 cylinder, does anyone have a vintage 1/2" NPT "K" valve they want to sell? Thanks!

Actually, these are a bit different than NPT called NGT (National Gas Taper).

I might, I have an old pony made from a 12 cu ft fire extinguisher sitting in the garage. Let me remove the valve and look but it may need service.
One of the reasons I stopped using it was because it leaked down over time.

Thanks, it wouldn’t be a big deal (if it leaked slightly) as I think I will fill it with a larger tank.
