Sultan Abdulhamit ordered these guns from the renowned German Krupp factories to defend the Dardanelles. They could should 276 kilo grenades from a 11,37 meters long barrel. This particular gun (there were two, but one was lost when it dropped into the sea during transport) was dedicated to, and named after, the man who, when the winch broke down, lifted these 276 kilo grenades to the gun at Çanakkale , private Seyyid. I have in the Çanakkale gallery a picture of the monument to his heroism - you can return here.
And in 2006 I found they had added a statue of the man next to this gun. Also, I was informed that this statue has a copy (or v.v.) in Çanakkale. It seems to better represent how the grenades were carried. But in December 2006 when visiting Çanakkale once again the statue turned out to be dýfferent from this one. Early 2007 you can expect new pictures of that one.
