Not nearly the same. The Model 22 recreation of the 1917 still appears to have the "infernal" lock and is no where as pretty as the original. Different grips and different stamping.
If authentic, the gun up for auction is a piece of history in pristine shape.
TW: yeah, for what this might bring a $50 authentication letter from S&W would seem to be in order. It could drive up the price as well.
From what I can tell it has all the markings according to "the book" and the s/n is in the right range to be early WWI.
A near mint one in the 75xxx range with factory letter and factory installed target sights went for $14k+ not too long ago.
LATE BREAKING NEWS (10:15pmEDT): Just got an email back from the seller and he does NOT have a letter from S&W. He should have. It could add several thousand to the bidding. I'm sure as word gets around the S&W community over the next week, it'll will be held up to scrutiny by collectors.
