Hi there, I recently found this little gem at a local jumblesale in Scotland. I have seen similar clocks on the internet, but they are all marked KM (Kriegsmarine), however my one is stamped with a crown and an "M" below. Also on the dial is the name "Wilhelm Kophamel Kiel" and the serial code "4325". Can anyone tell me anything more about it, does the name denote the boat it was on? Also, is it as rare as the Kriegsmarine examples? Any information greatfully received. Many Thanks
