Listed for sale is a World War 1 / World War I British Small Box Respirator B. S. B. These masks were used extensively throughout World War 1 by the British, untill phased out in 1921 by another mask. These masks nowadays are becoming quite rare to pop up compared to U. Small Box Respirators (Corrected English Models), and when found are usually in very rough condition, often with filters extremely rusted, often literally rotted away and missing completely, and facepieces that are so hardened, they’d crack and tear if opened. This mask is entirely intact, the lenses are still transparent, and there are no tears in the cloth, and very little wear. As is usual with these masks though, It’s not in perfect condition as It’s over 100 years old. The mask is a little bit stiff, though still pliable to model, as is the hose. The filter is rusted, again common with these masks, but is wrapped in cellophane with a decent amount of It’s original enamel still intact. The outlet valve is not original, It’s a piece from an old U. The instruction’s and field information card is still intact and unopened on the filter.
