Any comments/info would be appreciated
A strange
(with serious weakness & errors in its design) but very interesting design (
for this era/year => 1912)
You are sure it is a 1912 design
It is an official design of the British Admiralty or it is a private design
(I think rather to a private design)
For this period, it seems to me very advanced, very "ahead of its time" design (=> a carrier-purpose built design)
(usually the early world first seaplane-carriers of the 1911-1914 period are much simpler & are from coastal-steamer civil ships or ageing warships conversion)
For a British ? design, the six single guns at the back, I imagine it must be either a
BL 6"in/45cal Mk XII or a
BL 4"in/45cal Mk VIII or a
QF 4"in/45cal Mk IV gun model ???
(very doubtful imagining AA guns in 1912)
