Here is a link to the article; I was not able to come up with any additional info beyond what was published in 2006:

I'm tickled some think it's a fake, but I assure all it is not. I had it at KRA @ 2005 or 2006, and the general opinion was that it was the real deal albeit heavily worked over during the course of it's life. I know where the piece came from, and there was certainly no deceptiveness there, and while it is a VERY funky piece, it definitely had a great deal of real age on it, so there is no question (none) in my mind that it was exactly as represented. This is one of the few heavily modified rifles that I was actually happy to see left alone, as it was extremely interesting to view the "story" of the transformation from rifle to bird gun.
I would not have wanted to shoot it, although it shouldered well. I would be sporting quite the bruise.
I am also quite surprised that it has not been shown anywhere, or "restored," or whatever, as the buyer was quite a prominent collector.
BTW, Muzzle Blasts only holds the copyright for one year, after which it reverts back to the author, so nobody need worry about copyright infringement.
I should add that a few folks in Carlisle were of the opinion that it might be an Angstadt with a long-ago replaced barrel. I could go either way on that one, but it sure fit the channel pretty darned well.
