When the QE2 ran aground in 1992 in Marthers Vineyard the props were damaged & parts were sent away to be examined.. when they were returned to the ship, the Tech stores manager gave some pieces away for paper weights & I have a couple of bits, you can see where they where ripped apart....
I am thinking about gettings these cut up & put on plaques with the date etc, I have now noticed on the round boss part there are some stamped numbers, 2543-7-6, mean any thing to any one?
