I received an email from a Boomershooter saying the 1917 Browning (here, the bottom picture in this post and picture 12 here) he had at Boomershoot 2008 "is up for sale at Cabelas gun library here in Post Falls. Boy it’s a magnet to pull people in!"
Post Falls is in north Idaho near Spokane Washington in case you are interested.
Update: Due to popular request I inquired about the price and got this reply.
