I have a new-to-me round label Aqualung RAM in excellent external condition that also had a fair few upgrades before I bought it (Cyclone, HPR, DBE, silicon exhaust valves and diaphragm, can clamp).
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)
