I just looked into this not too long ago, when a user on another board put forth a question on building ownership.

I found this article with a lot of interesting claims.

Be forewarned that the author cites a book, to which, he himself contributed. I am not vouching for it's veracity.

It claims the owner of the building to be David Harold Byrd.

Harold Byrd's oil wealth," Cridland continues, "granted him entry into the inner circle of Texas power. He was a member of the 8F group, an elite organization named after the room number of the Lamar Hotel in Houston where they held meetings. The group of predominately right-wing business men had Lyndon Johnson and John Connelly in its ranks. 8F also coordinated political activities with other Southern right-wing politicians and businessmen, including Billie Sol Estes and Clint Murchison. These are names that are very familiar to researchers who have investigated Lyndon Johnson's connections to the JFK assassination."

Harold Byrd bought the building in 1939. When he returned from a suspiciously-timed, two-month African safari in January of 1964, Harold Byrd had the window that Oswald allegedly fired from � the window of the sniper's nest � removed and kept it as a souvenir.

"He morbidly decorated the bottom half of the window with newspaper clippings of the assassination," Cridland writes, "and postcard pictures of Kennedy, Dealey Plaza and his Book Depository. He framed it and put it in the banquet room of his mansion, where it remained until the day he died in 1986."

Who does such a thing? Unless, maybe, it's some kind of trophy. BtW, the question mark icons are from the original.

And, yes, he is a cousin of, Richard Evelyn (isn't that an interesting name) Byrd. I was unaware of the Admiral's ties to the brick layers and that he had established Antartica Post #777

Anyhoo, the article is an interesting read.

From pole to pole, 😉 it sure is a small world.

I don't think we're ever going to know the real and complete truth.
