Andy,
Don't know whether you have checked this:
http://www.wehrmacht-awards.com/foru...d.php?t=488912
Quite interesting. Godet & Sohn were a very old, well-established company involved in military awards, etc.. The thread runs to 20 pages (which I have not read!) so there must be a lot of info on them.
I hope the above link takes you a little further in your quest to determine the authenticity or otherwise of the item.
Edit: At the bottom of the first page in that link it says as of 2011: "The on-line Berlin phone book shows there is currently a "Gebruder Godet & Co." presently at Wieland Strasse 16, 10629 Berlin (Charlottenburg); phone number +49 (030) 3244223
They are listed as being in the wholesale trade of books, magazines, newspapers, music and other printed matter."
