Hello! I managed to get two triax male connectors, extinct brand "Specialty Connector Co., Franklin, Indiana", vintage 1990, kind to be screw assembled. The part code is 30P100-1. I also have a triax 2-lugs male/triax 3-lugs female adapter, part code 30A103-4. Specialty Connector Co. became Berg Electronics, then FCI, but there isn't any trace on their web site. Someone has a catalog, data-sheet, assembly instructions? Those things have too many pieces, they bear some resemblance to Pomona 5218, but it's not the same. Best regards, Andrea Baldoni

I still didn't find assembly instructions. Best regards, Andrea Baldoni
