In a different generation of these accessories, the part that screws on to the amplifier/body (KA 100) was a solid piece with the Lemo socket built directly into it. I currently have a pair of those for sale in the Yard Sale, with a different photo from the one shown here; the photo here shows what was then called simply the LC 3 (= the capsule end of this arrangement plus the extension cable itself) with one of this type of KA 100.
