Prussian Observer Badge no maker mark silver on brass?

[Oceansider]

This is part of a group of insignia that has been offered to me. It was photographed under less-than-ideal conditions. It has the tarnish of silver with some green verdigris from brass, so i assume it is silver over brass. There is no maker's mark I can find.

Any thoughts?

I certainly like the look of the badge. Pity about the missing pin!

To me, the basemetal looks like steel or zinc, not tombak. Ask him to put a magnet on it. The hinge and pins for the chequered box may be tombak, just as there may be a copper component to the solder, which are the areas the verdigris is limited to.

The pins that secure the observers bade to the front may be plated brass hence the green verdigris
