Cast iron and brass teapot, very heavy, no markings to denote era or maker

Large, heavy cast iron and brass teapot, with a dragon forming part of the handle and spout, and the Arabic word 'Allah' in brass on both sides. No idea of origin, age etc there are no indications or marks on the outside. My father has owned it for a while, i think he bought it from a friend of his and no idea how the friend acquired the piece. Makes a wonderful and eye catching piece.
