Hi, I looked on the web about this Company from a link from another forum and the website says they also made "pressed armoured cupolas for armoured vehicles also" Perhaps this was attached to Cupola, as it seems to be of a Military format of data plate?
I was not sure what this was from when I posted this thread, a stab in the dark really. It would be interesting to know what R1/5904 is?? Guessing this was perhaps the item coding. Interesting the company made items to do with Peenemunde.
Here is the website.
