Sorry, fake. Is this listed in an active auction or do you already own it? If you bought it, you need to insist on a full refund from the seller. The serial # and the creed stamping are both wrong, among other things.
"every indication is that it is authentic" - not at all, I'm seeing something in almost every photo that's screaming "fake". It doesn't even look as if the creed is stamped straight, and the font and spacing of the words is wrong - even the wording is wrong.
BTW, when asking for authenticity opinions, please use the format set down in Post #1 on Page one of this thread - thanks!
