I saw the lanyard, but still cannot figure out what method of ignition they used. Friction primer?. Impressive pictures. After seeing some of these and other posts have come to the unshakable conclusion that the big ones are there for a reason. No one has the equipment to haul them off. kings point merchant academy in new york had a 5"38 deck gun as one of its memorials. Was there some years back attending some courses. Keep the pictures coming, may never see those guns in person, but its nice to see them online. Happy New Year all. Frank
