Early mouthpiece valves
This is from a very early Mar-Mac catalog. I think it shows pre-USD or Hope-Paige non return mouthpiece valves.....In the ad it looks like they are being put into an early one piece mouthpiece assembly. It is a large photo so give it time to load when you double click on it. I tried to make it large enough to see the detail. A friend of the forum sent it to me.

Doing it right should include some common sense, not just blindly following specs and instructions. .Gary D, AWAP on SB
