1914 An Anchor Line ship - they were part of Cunard for a while, which makes me wonder if there was something about the ship that kept Cunard from slapping the company name on the vessel.
For that matter, I don't know why this card exists. It was never a passenger ship. As soon as it was built it was requisitioned as a troop ship for the Great War. It took a torpedo in 1917, and another British ship came to its rescue - in contravention of the usual orders, as far as I understood it. The U-boat fired another, hit the Transylvania, and down she went.
The captain of the U-boat died in his bed in 1966; his son, a U-boat commander in WW2, was sunk by American munitions.
