You can use it as you choose but photo coutesy needs to go to NPAWC, thats all. I actually took it, but, it belongs to my employer. Unfortunately very little is known about the owned, and the badge recently surfaced, so have not had time to have the pilot's name (engraved on back) checked out, as it is in Japanese. When I am next at the storage facility, I will pull it out and take a photo of the reverse side if you like.
Also, check this one out, it is Galland's from the Battle of Britain.
