This is one of many helmets found from Scan The World's grandfather's basement. Copies of such helmet can be found at other War museums.
The Pickelhaube, was a spiked helmet worn in the nineteenth and twentieth centuries by German military, firefighters, and police. Although typically associated with the Prussian army, the helmet was widely imitated by other armies during this period.
In accordance with the 1915 regulations Pickelhaube would no longer would use brass, silver, or Tombak. All issued Pickelhaube would now use grey oxidized steel fittings for all Regiments. For units such as cavalry etc that wore brass or Tombak chinscales, these were replaced with a M91 leather chinstrap. The spike was now removable and fit into a corresponding bayonet-style lug on the round spike base as shown on this Model 1915 Saxon Infantry Pickelhaube.
