I have several of Frank’s photo albums. The photo post cards are probably not new to the world but they add some more details of life aboard the Lion.

H.M.S. Bellerophon. At Jutland she was commanded by Captain Edward F. Bruen in the Fourth Division. (From the Wiki). Fired 62 rounds but did not receive a hit.

H.M.S. Centurion In the Battle of Jutland, Centurion was commanded by Captain Michael Culme-Seymour. Firing four salvos of her main armament at the Lutzow, she took no hits. (Wiki) Frank was originally told off for the Centurion, he was in the picket boat heading over to her, but was called back for the Lion.
