Thanks to Sandy we now have the German 1897 regulations that specify the composition of the "Tombak" used for the 1895 Wappen (https://www.pickelhaubes.com/xf/thr...-for-pickelhauben-and-shakos-from-1897.18596/), as 86 - 89 % copper, 14 - 11 % zinc.but I think that the Bekleidungsordnung is referring to the golden-coloured tombac for the 1895 Wappen
