Don, you're on fire! Early pipe (Pre-war), and marked as a Straight Grain! Does it have the metal mortise reinforcement?
Quoting myself,
"Some more historical information, The Blue Riband is an unofficial accolade given to the passenger liner crossing the Atlantic Ocean in regular service with the record highest speed, and dates to the early 19th Century, with the Cunard White Star Liner, Queen Mary, ultimately posting 30.99 knots (57.39 km/h) in 1938.
The last vessel to hold the title was the SS United States, on her maiden voyage in 1952, the United States upped the Blue Riband to 34.51 knots (63.91 km/h). In 1958, the transatlantic airlines put jet transports into service and the days of the record breakers were numbered. Queen Mary retired in 1967, and the United States in 1969. The United States is still berthed in Philadelphia, with ongoing efforts to preserve her, and save her from the scrap yard. "
