I'm a volunteer at a factory museum that did ww2 armament for the Allies and the Axis. And we have this suitcase that nobody knows what it is. I could be nothing related to the ww2 era. What we think it could be is a "speed velocimeter" for the bullets or even just a controller for the cutlery bath (they did that after the war was over). 1- The suitcase case it self 2- The first paper. It shows the suitcase and the other thing. 3-The other paper ( in Portuguese ) It says: B I Batteries I and II B II E I Chronograph I and II E II A I Target I and II A II Pendulum c.f fixed contact c.m moving contact P I Permutators I and II P II Komutator (?) connector I I Invertor I II D Circuit Breaker 4- The other thing. That's pretty much all we have for this. And sorry about my poor English.
Thanks. Thought that might help, but not so much. I'm going to post these pictures to a forum where they love doing this kind of thing. And please, what country are you in?
Isn't it something to do with a Chronograph? The Schematics for setting up the Chronograph (easy enough to translate) is what the drawing is and the bottom half of the drawing matches the bottom half of the suitcase in that first picture. I wonder if its something related to Artillery in this case? I am not sure if its WW2 era or not, just deducing from the information provided.
Another party thinks artillery as well, specifically timing shells in the air. He suggests this book as a possible source: Description of a Chronograph, adapted for measuring the varying velocity of a body in motion through the air, and for other purposes ...

Oh, sorry for not responding, I'm from Brazil and on one of the papers it is said "Cronograph" somewhere, I was wondering how it worked and what model it was. I think I have it all now. But I'll let this post open for posterity. Oh, and the funny part is that I don't find anything related to that elsewhere
