You have indeed been most helpful. I dare to call myself a sculptor
and even allowing artistic licence. It is no surprise to me that the possible inspiration for this piece can seen. I have been able to nab these pictures of Turkish bayonets . There is a Belgian bayonet that is also a reason able match. I feel the Turkish bayonet has a definite chance especially After research. I have always felt this is West African work. The Ottoman army fought in North Africa, Libya, Sahara and into French west Africa. The Ottoman army was obviously in Egypt and the Sudan and I believe units in German East Africa. However I am not an expert and the item does not seen East African. I strongly suspect that it is from the regions around the borders of French West Africa and the Sahara of North Africa if that makes sense.
