Hollow version of NSKK helmet shield. Believed to be finished in brass and unmarked with one prong still remaining. Some corrosion on the front and reverse of the shield. Definitely a been there piece. Recent discussion with other collectors have also revealed that this was used for a very short period of time where it would be mounted onto the NSKK motorcyclist's helmet. However, no period photos exist to confirm such claims. From author's own collection.
