Gyroscope for a Whitehead torpedo

[Natter]

My expert-friend is 100% sure a Zeiss "fabrik-nummer" should be stamped in somewhere (small letters, 5-siffre number).
His currently best guess is that you have a Richtungsweiser-Sehrohr C/XXVI (ie pre WW2).
He is interested to get in touch to discuss the possibility to get some photos of your device - maybe you can give me your adress so I can forward it (send me a mail at bergen31@yahoo.com )?

I had a second look and found this (I think):
"Facherschuss /sec.X0,8 sec."
I guess this have something to with some kind of shooting. Maybe it is related to the aiming of the guns of the "Königsberg"?

Facerschuss = Salvo. It was a normal tactic for surfaceships to launch 2, 3 or 4 torpedoes (depending on type of battery) in a salvo during an attack. The torpedoes were separated by either a time-intervall, by means of a slight individual course-variation (pre-angling of the gyroscopes) or a combination of both - ref the attached illustration from a norwegian post-war coastal-artillery manual.

The only "serial number" I can find is "Nr. 1". I am however not sure if this is a serial number.

According to the expert, that is the navy's propertynumber (first periscope made), while the fabrik-number is the manufacturer's number (Zeiss).

Thanks for the information and especially thanks to Natter! The serial number is: 53586. From what I understand, the item shown here is a part of a german «Richtungsweiser-Sehrohr C/XXVI» for torpedos. If anyone has a picture of such an item, it would be nice to see it!
