I've watched this thread for several days now, much of the back and forth BS is amazingly closed-minded and the negative comments serve no helpful purpose. Being acutely aware of all that concerns this gun, I'll try to clear the air a bit....
First, although I don't nearly always agree with Murph, he is absolutely correct as to the validity of the Tiffany markings on this gun. It came from a prominent antique collection that dates to the pre-WW II years and was vetted by several Tiffany experts, including a retired company archivist, before being accepted for consignment in the auction. Research prior to the auction confirmed the acid-etching matches a number of known Tiffany items, not just guns, some of which - like this gun - were 'used' when embellished. And there is no doubt the barrel was professionally cut to 4" prior to the etching being executed.
Second, as Murph also correctly stated, the current owner IS, in fact, a well-known S&WCA member who knew exactly what he was buying, as did at least one of the underbidders that some of us are also well acquainted with.
Critiquing from a lack of knowledge position = 'talking without thinking', first or at all. Having nothing to back up a negative opinion, other than a negative opinion, does no one any good, especially in this small world we all play in every day.
For what it is, the gun is unique and different, and right as rain. Give it and the owner a break, and simply enjoy seeing something very historically cool from well over 100 years ago.
