RE: CCa Siemens Identification (with actual photos)

Hi Nunki, thanks for writing.
You could elaborate a bit, because first time I hear this for a Siemens tube that could be dated 1968. Unless the code system changed after the Munich factory closure and confused those after 1979 with those made previously.
Anything is possible.
