Hello - I am not very knowledgeable in the area of uniforms, but have a few uniforms and hats in my collection. One hat is an overseas type (Bordm�tze?), the exact shape/style as the one shown by Gary B. The exterior appears to be dark blue wool and the interior a medium blue rayon. Excellent quality, but it is unmarked.

The only difference is in the the piping and the police style eagle, which are silver. Possibly not WPP, but what?

Thanks, Dan
