So after some seachng found out this is US Navy..Line enlisted pre WW2 cover, or an officers missing gold strap.ehh, not for my collecting, so out it goes

This is a USN Warrant Officers cap, missing the gold strap, circa WW2.

Scroll down here to Warrant Officers https://www.uniform-reference.net/insig ... ficer.html. A Chief Warrant Officer would wear a regular officers cap, a Warrant Officer would wear as above.
