I think someone has 'denazified' it to hide the fact that it's a cast fake, but the opinion of a true expert is the only thing I trust at the moment! Thanks in advance.
I did a bit more research, and I realized that the ring is wrong, being made from a bent piece of wire, so none of this is original. Never mind, and apologies if I've wasted anyone's time.
Yes, this is a fake, it lacks the quality found on originals, there are several 'pimples' on the surface which is a bad sign and the makers mark should never be seen on the suspension loop. The ribbon is bad as well.
Looking for LDO marked EK2s and items relating to U-406.....
This is happening an awful lot on auction sites, especially E-Bay Germany, which is awash with them ! and the practice is spreading here......not content with trying to rip off collectors with out and out fakes of TR awards/badges and medals etc, the fakers have now decided it may be more lucrative to de-nazify those fakes, and sometimes "1957" them, in a further attempt to get you to spend your hard earned cash..........buyer beware !!!!!

Thanks guys! I thought as much, but was concerned that it may be mostly fake rather than all fake. The scammers are getting better. People are less likely to closely scrutinize a denazified medal. I think the seller of the one pictured above was clueless, though.
