Ruby's gun disappoints at auction.

The .38-calibre Colt Cobra revolver nightclub owner Jack Ruby used to shoot presidential assassin Lee Harvey Oswald, up for auction in Las Vegas, got a bid for only a fraction of the owner's $1 million minimum asking price.

The gun, part of a weekend pop culture artifacts auction, drew a top bid of about $200,000. That's the same amount gun owner Anthony Pugliese III, a Florida real estate developer, paid for the weapon at a 1991 auction.

The Pugliese Pop Culture Collection, on the auction block Saturday and Sunday, includes about 150 items associated with President John F. Kennedy or his assassination in Dallas on Nov. 22, 1963.

Auction house Guernsey's said the gun might be sold privately.

Ruby purchased the gun in 1960 for $62.50. He used it three years later to kill Oswald
