MRODAIR AIRMAX II pressure gauge

What size threads are on the pressure gauge of the Mrodair Airmax II. I am going to get a new one. Where can I get one for a reasonable price? I just don't know which one will fit the air cylinder.

I have purchased some gauges from AliExpress, I’m not very knowledgeable about figuring out the correct sizes, but there are assortments available.
1/8 npt male thread fits the Benjamin marauder
M8 fits the nova vista line
There is m10 as well but I have not needed to buy one of those yet.

I have two spares that I bought direct from China when I ordered a bunch of parts from SPA.  I'm hanging on to mine because I have more than one SPA gun and it's always nice to have a spare.
