This is a rare U.S. Navy N-1 deck cap from the 1940s, featuring stencil markings for deck crew members. While U.S.N. logo stencils can still be found, stencils from this era are considered scarce. In my opinion, the wear and tear of the period is fantastic, and it's a wearable vintage piece that can still be used. The size tag is 7, but it fits me perfectly, and my head size is about 57.5cm.
