Hello, I have this filter, clearly its German (Austrian address) and WW2, but why is it red? is it for training? Its is exactly like a normal filter except for the colour and label. With thanks, Doug

Non-military? Chemical laboratory filter?

Brandgasen = fire gases, perhaps for firemen ? So, red color....IMO
