Vintage 1940s WWII? Military Navy Knit Brim Hat Cap Very Rare! USA Army

Wow! Very rare hat from the 1940's era.  Not sure if this is military issue or not, but looks like it could be a navy issued hat.  Either way, it's an extremely old knit brimmed cap. In worn vintage condition with fading, some light stains, leather brim is cracked in a couple places, scuffs on hat top button, some discoloring under brim, and hole under underneath.  Selling as is.  Please view all the pictures scrolling/zooming to determine if the condition meets your satisfaction, you will receive this exact hat.  No Returns. 

 I do my best to describe the items as accurately as possibly, but keep in mind these are used, pre-worn, selectively curated pieces (unless indicated new condition).  It is IMPORTANT to read the full description and view ALL photos carefully.   If you are unsure about (size, color, measurements, condition), please feel free to message me. Thanks!
