unknown device in a German torpedo
- Thread starter William49
- Start date
Not a book but a much "scientific style" archival file of Werner Osenberg about research to improve small details of torpedo internal parts and measuring devices. It's not related to ordnance thematic like torpedo fuzes etc.
Werner Osenberg was a key person which made the US „Operation Overcast“ possible because he handed over a list of 15000 German scientists to the USA. He seemed to be a very intelligent person but as a NSDAP and SS member he must have been also a 101% Nazi.
Some interesting info about him you'll find here: https://de.wikipedia.org/wiki/Werner_Osenberg

It's a standard recordingdevice for depth and roll. There were several models, and the one posted initially is not the same as the one in the merkblatt provided by Alpini (witch shows a model with an electrical controlled/timed recording needle).
I don't know specifics of the model with electric control, but these devices were pretty similar and normally driven by a mechanical spring acting upon the two heavy "flywheels" seen at the bottom, providing the power for the recoring device. The recordings were done by two mechanical needles "scratching" lines on special paper moving from one roll to another (a hydrostatic device controlled the depth-recording needle, and a pendlum controlled the roll-recoring needle).
The prepared recorder (ie equipped with a blank paper roll and a winded-up spring) were mounted in a dedicated pocket in the exersicehead. Depending on the model, it was activated/started by a flap being pushed back from the waterpressure, or a pendolum reacting on the kinetic energy from the launch of the torpedo (the model for which a merkblatt is provied is of the latter variant).
Most countries had such devices and they were very similar. For post-WWII usage on the ex-Kriegsmarine torpedoes in the Royal Norwegian Navy, we used mostly british models with an adapter to mount them in german exersiceheads. I have attached a drawing of the british model (model 1928 if I remember correctly), as well as a photo of the recorders we have in storage at Herdla.

Nice, do you have the complete roll and/or others from the T-178 publication? I assume they are not digitized and available for download from NARA...
I'd be very interested in obtaining copies of those, and happy to trade (for instance, I have about 3500 rolls from various publications in RG 242).
Hi Natter
-I am asking you for a contribution to 21cm ammunition from Norwegian sources...
-For the operation with the T-178 ,
I have no problem changing only the RG-242 is not quite my goal .. do you have anything else (ammunition )

Ok..? Record Group 242 is all the foreign seized material at NARA, ie German (the largest part), Italian etc records (including over 30000 microfilm rolls). Tons of documents on ammunition as well in there.

I have litterally a few million documents from various archives (including ca 3500 NARA microfilmrolls of german records). Problem is, I have no detailed inventory, so it's hard to find specific documents - especially outside my main area of focus (german coastal defence and underwater ordnance). I can certainly assemble a varity of for instance german munition-documents though (I found ca 800 documents on one harddrive right now).
