Hello Philippe,
yes.. Niedersachsen.. Bremervörde
My main "collecting stream" is the SA and the Luftschutz... and i´m a Iron cross Messi
I looked a long time for a Pickelhaube because i love them much.. After getting my one now i´m sure that the "Kaiserzeit" will be a new part of my collection..
My Grandpa was in the great war a member of the Infanterie Regiment 16 (Freiherr von Sparr, 3. Westfälisches) and was wounded at Verdun... Maybe i will look for Items from this Regiment.... and for sure.. more Pickelhauben.. i think my next one will be a prussian..
