Imperial Japanese Navy Radio Operator GasMask.
I'm quite happy to own a piece I have been looking for years the bag is quite small compared with the other navy mask's bags I have.
The filter is my first filter with harness. Also It came with some accessories that the seller didn't mention, it was a good surprise.
The mask is a bit dry but still in great shape.
The box has the navy symbol, but I actually don't think it belonged to a gas mask.
I hope you like
