I picked up this one a couple years ago. I tried to do a bit of research, from what I understand it is an NCO visor that was upgraded to an Officer rank? Would this be WW2 era or post war?? I don't normally collect this kind of headgear. But it looked nice so I grabbed it. I hate to ask, but can somebody give me a rough idea of what this would be worth? I don't even have the room to properly display it, it doesn't see daylight often and would probably better off in someone else's collection.
