I'm picking up a new/old boat that I believe has older negative pressure Cliff Shaw guns in it. Does any have any info on these systems. Links, Schematics, PDF's, History, Pro's & Con's, Anything? Just trying to get a heads up on what to expect when I bring it home. THANKS
Check with Joe M. and Jeff K. in WWCC both have worked on this type of cannon. I believe if I'm not mistaken Joe's Iowa still uses 1/4 triples of this type.
