Hi Collectsmedal,
Thats an awesome and pristine M15 Prussian pickelhaube you have there!
The liner is simply awesome, thats a killer liner! The helmet itself looks very smooth and very little crazing. Thats somethin very rare for a 90 plus years helmet. You dont get haubes in that condition often.
It looks almost unisued, could this be one of those helmets came from a clothing depot which was ransacked by the Allies?
Could you pls post a detailed pics on the round maker's mark, pls? It seems that there is a 1916 mark, too.
Thank you so much for sharing this superb condition M15 haube, thats simply a killer haube.
Cheers,
Mush
