#54709, "RE: Mauretania bridge top mystery structure " In response to In response to 16
Nice catch on noticing the Lusitania's second compass platform. For reference, I'm attaching a unique photo of the Lusitania's Bridge Roof, kindly loaned to me for the 2015 edition of my Lusitania book by artist and collector Stuart Williamson. I've watermarked this cropping to protect his rights.
The second photograph is a port profile from the Library of Congress, available in high resolution from their site. It shows both compass platforms ca. winter 1914-1915.
