Help with Helmet

[Jim's Militaria]

I am new here and need some help with a helmet. I recently picked this helmet up (along with two others) at an estate sale. I think that it is Third Reich police from Coburg or Thüringen? Any help or information would be great.

Thanks in advance.

Cool piece, looks like Third Reich police helmet

The Radecke Police helmet books show a similar plate on a Shako for Thuringen
