Button Prussia 27mm - please have a look

[Dickdan007]

Hello,
I have a button from prussia here. Diameter 27mm. The manufacturer (A. & S.) Is Assmann?
Who was he wearing? Army? And when, in the first worldwar or earlier?

Thank you

I think it is an NCO rank Collar Disk, not a button.

Jea, good boy!
look here: world war 1 | Portraits of War
its a rank collar disk from a Sergent.
What is: NCO?

[christek]

Non-Commissioned Officer such as a Sergeant or Corporal

one more question: on the eagle is not "FR" for Friedrich Wilhelm.
Was the button worn earlier? Or in World War I?
