Just bought a police Pickelhaube with a slightly damaged wappen. Let me know your thoughts. https://www.ebay.com/itm/Pickelhaube-/133185968657?txnId=0#vi__app-cvip-panel
Not a bad helmet, I don't collect Bavarian police but liner looks nice. Seller has been selling haubes over the years, not a bad guy but somehow his stuff always arrive with broken arms or legs, so he got upset with me after I asked for a replacement of the wappen.
Nice helmet.
The helmet should have a Kokarde on the left side similar to a Raupenhelm.
They are generally not too hard to find on Ebay; however, there are many variations.
A little research should point out which one you need.
