Radar experts unite, Rotterheim radar ?

A friend of mine send me this picture. And this was my responce. Can anybody help with a pos. ID ?
The reflector is clearly a FuSE 64 Mannheim, but the carriage is not the one used by Mannheim, but by Naxburg. Further it has a small horizontal dipole which clearly indicates that it works in the cm band - my guess is 10 cm = 3 Ghz. This should make it a FuMG 76 Marbach, but the reflector is wrong and Marbach had a rotating dipole in a small housing a la W-R. F.T. has a picture of the dipole for an experimental Mannheim radar called Rotterheim, but no picture of the whole system. My guess is that this indeed could be a Rotterheim - and the only known picture !

The device shown has a differnt purpose, then what you expect.
According to Fritz Trenkle the picture shown is "Hörnchen".
"Hörnchen" is part of the "Celebes" ground (remote) control unit Hawaii II for the operational use of the missile A-4 (V-2).

Hi Christian.
Next time I'll check ALL my sources before I go public with my ignorance. The book you mention is within arms length, but I didn't ckeck :-(. Thank you very much for the help.

No problem SES,
we all have "our certain days". That's not a form of ignorance.

Hello,

Sorry for bringing up an old item.
It was the best entry I could find for my question.

I want find out if a piece of optics could have been
used on radar equipment (Flak ?).
The optic is marked with "Beob-F 12x60 für FMG 41 T."
(see pic below)
I have googled for FMG 41 T and other combinations, I found it,
but only in some textfiles and databases with tech specs of the radar.
I found one picture on Gyges with two of them at Grove.
Other names of this radar seem to be:
- FuSe 64
- Mannheim
- FuMo 221 (Kriegsmarine)

Does anyone have a picture of this radar which might prove
that it used an optical guiding instrument ?

Lenco,

Hi,
I have checked the Merkblatt on the FuMO 221 and there is no reference to an optical device. However all German radars were calibrated at regular intervals. A target tracking radar would be calibrated for range, bearing and elevation. I have seen pictures of various methods. On a Würzburg Dora there was a ring and bead sight, which could be used to verify bearing and elevation, and I have also seen Doras being calibrated with a theodolite. Your "Thingy" could be such a calibration device mounted co-axially with the normal to the radar antenna.
