DALLAS (MCT) — The big gun went for big bucks in the Big D.

An 1883 Gatling gun, owned by the city of Harrisburg, Pa., for a controversial Old West museum that will never be built, fetched $280,000 at an auction here Sunday.

Gary Hendershott, director of Western auctions for Heritage Auction Galleries, said the price was a record for that type of gun.

The weapon, still capable of firing 1,200 rounds a minute, was projected to sell for between $140,000 and $200,000.

The bidding also topped high-end estimates on the other centerpieces of the collection amassed by Harrisburg Mayor Stephen R. Reed over a decade using millions in public money.

A stage coach, circa 1880 and fully restored, sold for $90,000 and a Conestoga wagon, which rode the Oregon Trail in 1850, drew a $35,000 winning bid.

The three items were bought by anonymous buyers bidding by telephone.
