This is an original world war 1 brass fuze. This would have been attached to the end of a British shell. These then would  have been fired at german lines and trenches during the first world war. This example came from France. Sadly we do not know exactly where. This example is still covered in the dirt from were it was found. It could be cleaned up if you wished. This example has  lot of dings and dents as it has been used. It is also covered in  British army markings and stamps.
