Question about Fernseh KOD B&W cameras

G'day all. This thread is for those who know about German Fernseh cameras.

I have lately been viewing old episodes of the German rock music show "Beat Club" from the 1960s and in the B&W era the cameras clearly seen are Fernseh KOD 3" image orthicon cameras which were introduced in 1957. Info on the Fernseh KOD can be viewed in the following links http://www.fernsehmuseum.info/fese-kod.html http://www.fernsehmuseum.info/die-kod-einblick.html . Two example clips where the KOD can be clearly seen are in the following links:

http://www.youtube.com/watch?v=jPYe7HdX30A at 0:37-0:39 and a clear side view at the end at 1:21 (see attached image below)

Now what has got me intrigued is that the images coming from these cameras look as good as that of a 4.5" IO camera and with much less haloing on the spotlights whereas 3" IO pictures generally look a lot softer and have ringing vertical bars on the left side and there's much more haloing and other artifacts, this is going by seeing footage filmed on RCA TK-30/31 cameras from the late 50s and early 60s. So I am wondering if those KOD Fernseh cameras were initially fitted with 3" IO tubes and later upgraded to 4.5" IO like the Marconi MKIIIs or did they use better electronics to drive the tubes to give more accurate pictures or did they use more refined 3" IOs which offered quality similar to 4.5" IOs?

Had unique swingdown PC boards uaing silver plated sliprings & said to be reliable.
Came in 3" IO only--the secret to their performance probably the Fernseh IO tube (rebrand of some other Deutsche Mfgr?) were said to have superb linear grayscale & plenty of resolution (way more than VTRs or TV X'mitters could handle). This product followed of course by their equally stunning color cameras.

If this camera is all solid state except the IO, that would explain a lot. The TK-41 signal-to-noise could be improved about 8 dB (if I recall correctly) with solid state amps.
