Look at my first image… the OPV is retained (I just had the cap removed while adjusting the release pressure) the very late Snark IIIs replaced the ‘coin slot’ LP Chamber Plug with a 3/8 LP port adaptor as an OEM feature.
I propose to recreate these adaptors based on measurements from an actual OEM example I finally got hold of.
