WW1 German 19th Artillery Regiment Pickelhaube Cover

A rare WW1 German Artillery officers pickelhaube cover with pre August 1914 red stencilled markings of the 19th Artillery Regiment. Regimentally marked officers covers are very hard to find with the Artillery versions particularly difficult. Both numerals are applied typically in thin ink with age commensurate to the rest of the material. Within the top ball cover is old scrunched up newspaper which I have made no attempt to move.
