This is one of my favorites, it's a senior ranking officer's helmet of the KNIL (Koninklijk Nederlands Indisch Leger),
ie Royal Netherland's East Indies Army. The gold piping on either side of the front panel indicates rank of a Majjor and above. Quite rare....1880's
I was very fortunate to have been offered to buy it from a very old collector from the Netherlands. He has been collecting for decades and shared that few exist, but one other example of this model can be found in the National Military Museum in the Netherlands. I fwas able to dig up the info that accompanied it. I's a model1894 helmet. And as Schiavona indicated the maker is
Frans Pauwels, Fournisseur de la Cour, La Haye' - The Haque.
