WWII P-61 Black Widow Northrop Test Pilots Wool Ball Cap. Wow, where to start with this rare piece of headgear. Two tone, orange and black wool body. Sewn to the front is a machine embroidered on twill NORTHROP black Widow patch ( I have never seen this one before). Has the name VAN written in pen. Marked a size 7 1/8. Some minor signs of wear but overall excellent condition. This has been in our collection for a really long time, but like evrything else we have kept, something better has come along. What a great historical piece of WWII Aviation headgear.
