Help Identifying WW2 era German Photo markings?

by ShoukakuKaiNi

Sorry if this is the wrong place to ask, but I found a picture of the German Battleship Tirpitz, and I was having trouble trying to figure out what the stamped markings on the back are for. I'm 90% sure that's it's some form of cataloging but I figured someone on here might know exactly what it's saying.

The top line indicates it's a copy of an original photo "foto-doppel"

The second part of the top line is the address of naval headquarters, Kriegsmarine. W-haven is Wilhelmshaven, Germany. 50 Rhine Street.

Second line is the catalog numbers

Last line as you could probably tell is "reproduction forbidden"

The Drüppels created a large archive of marine photographs and sold postcards. Nachdruck verboten/Reprint forbidden is the equivalent of 'all rights reserved'.

The collection now belongs to the Wilhelmshavener Zeitung. http://www.wzonline.de/service/bilddienst.html
