content: so what actually is it ? looks like a handle to me. Don't forget that sinclair went by the by quite a few years ago. chances someone is using the name. it happes often. Like Quad still exist in name but it's just a front badge for some taiwanese made gear made by a company that just buys up companies and uses their original names.
