just scanned a list of old German Transistor Modules.
it's an overview of the older tube names, Siemens SiTral x2xx series, TAB / AEG - Telefunken x3xx series, Neumann x4xx Series (incl. the older P-names) and the AEG - Telefunken x6xx series (this one is not complete, the list ist older then this series)
