Thanks for that Lance
As I say I have always regarded mine as a later repro and have never paid much mind to it. It was given to me at a time and place I just don't recall so there is no issue of loss potential here.
Interestingly this video discusses an "original" German striking of this medal yet if I recall my history of propaganda correctly the Germans have always denied that such a thing was ever done (it would be extremely dishonourable in terms of the "rules of war" and don't see the Kaisers Navy being very happy about it) and the accepted line has been that it was the British who produced this and circulated the tale the "the dastardly Hun" was glorying in the deaths of non-combattants.
I know that history often needs to be re-written when new facts are discovered as evidence comes to light so perhaps I am out of date with this story.
Do you know of this medal being finally attributed to German sources?
This of course makes no difference to the "original versus later repro" debate as whoever produced it this is still a valid question.
Thanks again for the link which is helpful.
