A small note on sliding nasal bars. Many could be worn with the bulbous part at the top, then inverted to provide more facial coverage before entering battle.
I suspect the OP's nasal was, in use, a bit straighter & bent later in life. It may be possible to rotate it if the wing screw is removed so the small protruding stud at the base will fit through, acting as a grip when down, and a stop to keep it from falling out when up. I also suppose that the missing rivet holes may have been for attaching a liner and or aventail of sorts.
