A window prominently displayed for a dozen years at The Sixth Floor Museum as Lee Harvey Oswald's sniper's perch in the assassination of President John F. Kennedy is up for auction on eBay.

The starting price: $100,000.

It could be, as the eBay ad describes it, "perhaps the most famous window ever offered up for sale in the world."

Or it could be the wrong window, mistakenly removed from the Texas School Book Depository at 411 Elm St. by a confused worker in the weeks after the Nov. 22, 1963, assassination.

That's the argument of several conspiracy theorists and museum critics and the claim of a Nashville man who bought the building in 1970 and said he took the real sniper's perch when he lost the property to foreclosure.

Caruth Byrd doesn't buy any of that.

Byrd, son of the man who owned the property in 1963, said his father, Col. D. Harold Byrd, told a worker to remove the window several weeks after JFK's death because people were trying to steal chunks of it.

It was displayed for years at Col. Byrd's University Park home and passed on to his son when the colonel died in 1986.

"I had it here in my bedroom, and finally I decided to loan it to the museum," Byrd said.

He originally agreed to loan it to the museum for three years. But three became 12 before he took the window back several months ago, he said.

Museum officials "kept saying I ought to give it to them," he said. "They didn't doubt that it was real. They knew it was authentic. They just wanted me to give it to them.

"I said I'll just take it out, sell it and give the money to charity. It's just a piece of wood."

Byrd said he was annoyed by articles that questioned the authenticity of the window and by museum staff members who seemed dubious as well. Mostly, he seems eager to be rid of the window and all that goes with it.

"There was some negative stuff about it. There were articles that said it wasn't the right window because it didn't look like the window that was up there that day," Byrd said. "When it was taken out, my dad had it cleaned up. I don't know what they did to the darn thing.

"I'm just tired of it. We can go out and build a fire with it. It's just a window. Heck, I have no emotional involvement with it."

Deborah Marine, public relations manager for The Sixth Floor Museum, couldn't say whether the museum ever offered to buy the window from Byrd or would be interested in acquiring it.

"We really can't comment on that," she said.

And she said no one has produced any evidence that the window is other than what Byrd says it is.

"We were just really grateful to have had it," Marine said.

Byrd lives on an exotic game preserve in Van, Texas, near Canton, where he has 2,000 animals – "lions, birds, tigers, but no hunting."

If he sells the window, he said, he might roll the proceeds back into his preserve.

"What it goes for it goes for," he said.

Byrd's mother was Martha Caruth, whose family owned much of the land between downtown Dallas and Park Lane and donated the property for Southern Methodist University.

His father, a millionaire oilman, bankrolled the Antarctic expeditions of his cousin, Adm. Richard E. Byrd.

But Caruth Byrd is happiest in Van.

"I know everyone and everyone knows me," he said. "Here, you see millionaires in the cafe, and they can wear what they want and no one cares.

"You can't do that in Dallas."
