help appraising older Poseidon

A "big bore' mouthpiece is still available, through Silent Explorers and elsewhere; just picked up a few, for some friends in Mexico; can get them on all of the old 300s -- with a touch of lube . . .

I just looked again and it's the #3202 they have not the one for the Cyklon 300

They are from the 70’s I believe.

It's from between 50's-70's

There’s not a bore on any of my old 300s, some somewhat larger than others, that that mouthpiece cannot accommodate . . .
