Talk:Fly-class gunboat

Is this a fly-class gunboat?
This picture is from The Times History of the War, Vol. X p.213, published in 1917, where its is identified as "A river gun-boat on the Tigris". It is flying the White Ensign. It seems almost certain that this is a fly-class gunboat. Should we include picture this in the article? Verbcatcher (talk) 20:52, 2 June 2017 (UTC)
