Merchant Navy 1915 crew lists online from TNA

It's an indication of how quickly material is becoming available online that there's now new information since my Great Moments presentation to BIFHSGO on June 13.
Charles Drummond, my great uncle by marriage, was in the merchant navy. In my talk I showed an image of his Master's Ticket obtained through Findmypast and a web link through Ancestry to a WW1 medal card at The (UK) National Archives.
The newly available information is transcriptions of crew lists and agreements from the Merchant Navy for 1915. Online availability is thanks to the work of volunteers and the cooperation of the National Maritime Museum.
A search for "Charles Drummond" at http://www.nationalarchives.gov.uk/first-world-war/search-merchant-navy-1915-crew-lists/ found three entries. He was mate, age 29, born Blackpool on the Ashfield; then age 30 on the Aquilla, previous ship the Ashfield of Liverpool and; another list for the Aquilla.
