NEW YORK (AP) _ A record $52,800 was paid at auction Tuesday for an engraved pre- Revolutionar y War American powder horn, Christie's auction house said.

The 17-inch horn, which dates to 1756, was only expected to bring about $2,000 when it was put up for bid, said Christie's publicist LeeAnn Fahey. The winning bidder was William Guthman of Westport, Conn., a collector of American colonial memorabilia, she said.

''There was incredible heavy bidding on the phone and in the room. It was amazing,'' said Ms. Fahey. ''There are not many like this on the market. ... Whoever paid this price was very passionate about powder horns.''

The horn was engraved by a well-known engraver of the time, John Bush, and read: ''David Baldwin, Esquire. This horn made at Fort William Henery. Octobrye 18 1756.''

The horn had been in Baldwin's family until the auction, said Ms. Fahey.
