This rather splendid veteran's badge has its original paper retailer's label on the back in black and gold. The logo around the edge translated means the first regimental roll call of the former hussar regiment King William I, Bonn-on-the-Rhine.

This (9cm diamater) appears to be composed of two elements, the backing plate being the star of the Prussian Guard, but the central crown being more like the ducal crown of Hesse, which one finds on Hessian belt buckles in brass and anodised steel. My guess is that this is an extempore piece made in WW1 for Hessian Garde Jaeger battalions.

An other ranks helmet plate, which appears to be made of tombak with a nickel-silver finish, and has a painted bear as the centre of the device. This was worn in Berlin between the wars and into the early years of the Third Reich. The condition is average for its age.
