However it currently has the original long LP yoke with 'spare tyre' knob and I'd like to upgrade it to a heavy yoke for 232BAR HP tanks.
I already have a VDH adaptor nut but am unsure which models of heavy yoke would suit the upgrade (Conshelf 12-14-21 yokes are threaded inside, the nut needs a smooth yoke bore)

Any advice gratefully received
