Hello guys
I found something for sale but not sure what it is.
Can you identify this?
Thanks

Not sure exactly what it is, but I can see right away that it has the Luftwaffe BAL inspection stamp on it.....so that may help a little.

And it seems to be made by Junghans.
DRP means Deutsches Reichs Patent.
