http://en.wikipedia.org/wiki/HMQS_Gayundah
Its a Victorian era gunboat HMQS Gayundah (HMQS - in this case stands for Her Majesty's Queensland Navy, once of the colonies that later became Australia), was built in 1884 and spent all of its long career in Australia. It never took part in any military action and in 1914 was converted into a training ship. In 1921 it was stricken from the navy rolls and sold to be converted into a barge. In that guise it worked until 1958 when it was grounded near Brisbane to be used as a breakwater, where its remains survive to this day.
This is how it looked in 1912 after rearmament (I'm going to build it as it looked in the 1890s, see second photo):
In 1/700 scale the length would be just 52mm.
As usual I started the hull from regular sheet plastic, in this cause one sheet since the hull thickness is only 1.5mm:

After that I added the wooden deck from Artwox:

Since the casemate will be open from the back and I've added the internal structures and will add an 8" gun. I didn't go all crazy on detailing since most of it will not be visible anyway.

Next I've added the casemate sides and made a rough cutout of the upper deck:


Here is the ship next to a quarter to give you the feel for the overall size of it:
