Thank you for your response!
Everything on the board comes from the original pic I found on the net. That explains the time, bearing, range and the swastikas.
I totally agree that a German language version in the boxes would be more authentic and accurate. If someone knows what to put in there, just give me the info and I’ll fix that.
About the swastikas: I will of course make a second version without those! It may be easier to print it at a public place without those aswell
I tried to print it on A3, and as you said you got plenty of space to make notes in the margins.
I will also make links to the Solid Works files if someone is interested in editing the CAD file by themselves.
