Even mine is the same. Brass loses sheen over time due to oxidation. There are foul smelling liquid cleaners available in the market that you can use to get the sheen back. I prefer the antique looks
exactly,you dont see brass utensils everyday and now most of them belong to museums.So the brass case is a one good collectible.And if you try to clean it shines for somedays and again it oxidises.
