British ww2 motor cycle dust goggles in metal case 1943

Nice motorcycle or tanker goggle set from the second world war! The set consists of a motorcycle dust goggle and the original metal case. The glasses are cloudy with one small crack. The elastic band is still present. The metal case is in a used but still working condition. On the front it is marked Francis and sons 1943 London. The bandages were inside the case so a nice relic from the second worldwar.
