I just spotted this:
"Win My Quigley Rifle"
Do you think this was the one actually used in the movie?? For some reason, I was thinking it was in the Smithsonian. If it was the actual one used, wow! I wonder who won it!! Since the contest was two years ago, there's probably not a way at this late date to get a listing of the winners, which is supposed to be available for every sweepstakes, isn't it? But you may have to request it at time of entry.
Will Google that and report back if I find anything (though I doubt I will).
P.S. Okay, a little more information, though I still haven't found the winner yet:
"SHILOH RIFLE UPDATE:
On the Shiloh forums one member said this.
There were three made. Mr. Selleck is keeping one, one is being donated to the National Firearms Museum, and one will go to some lucky person.
Also said on the forum that a couple of solid barrel ones were made for stunt work and a couple of 'rubber' ones were made for the fight scenes.
So this Shiloh rifle is one of three, thus creating the high ARV ($102,000) for the winner to pay taxes on."
I also found out you had to send in a SASE before the end of the contest to get the official list of winners, so no luck finding out from the NRA contest section, I guess.
