You'll need two different barrels.
Do you have availability of a barrel for the G200 upgrade? I have the other parts. Also, did I notice at one point you are located in SE Asia? We just returned from a great 3-week trip.

G250HPOkay. We are back from vacation, my Scubapro tool kit arrived and I just took the cover off the “mystery” 250 (or 250HP). Pictures attached. The case has the “pebble” finish. The adjustment knob is bigger/different than my “regular” 250. It says “DIVE” with some “directional indicators.” So, assumed it was an HP. But, opened up the case and it has a metal air barrel. Looks like the inside of a 250. But there is an extra plastic plastic piece near the adjustment knob end which appears to be related to the adjustment mechanism. One more piece of information/clue. This 2nd stage came from a set with what appears to me to be a MK15 DIN with a Yoke attached. Also, the SPG measures BAR. So, what do I have, folks?
I don`t think a regular G250 air barrel will work on what`s in your pics. The adjustment knob is different.
G250HP
The G250HP is backwardly convertible (air barrel change required) to a standard G250; but not all G250ies (non-CE models are not) are convertible to the HP.
It will not.
Second thoughts... the cases are almost identical, I think you can transplant complete barrel assemblies into either case but not partial, you can't mix and match adj knob ends.
MK20 DIN with yoke adapter.Thanks!! Did you get a chance to look at the 1st stage pic? Is that an MK15 DIN?

Re the HP-yes, service it and keep it as it is.
