Not sure what to make of this. It is a WWII issue Civil Defense helmet with a PD decal on the front and identifiers on the inside that indicate it was issued to at least two different patrol officers in the Bronx, NY.
I can't figure out if these were issued directly to the PD or they were surplused to them post war.
It was pretty dirty when I got it so I did wipe down the exterior, left the interior alone due to the handwritten markings.
