I haven't purchased the one above. I was interested in it and didn't want to get ripped off again. I collect military memorabilia and these are hard to authenticate.
The fake I ended up returning to the seller and getting a refund. I tried explain how it was not real and he didn't believe a word I said. I showed him proof where the Navy Seabees actually made them and traded them off. Oh well. I learned my lesson.
If you're not in a hurry, wait for @Toritoribe to give you a much better informed opinion on it than I can. I think he's currently tied up with RealWorld stuff for a bit but I expect he'll be dropping by before too long.
