We have a saying in the UK "you wait all day for a bus then three come along at once"
This; I do not think is "Trench Art" To my mind the carving is very nice and not the product of a soldier passing time. I would suggest that the 303 bullet and casing has been added much latter spoiling a super staff. It went for rather a lot of money too. It could still be a potent sybol of the power of the Oba but the bullet would still be a latter addition which is a problem.
Is there such a thing as WW2 trench art?
