Help to identify Prussian Epaulettes

[donkeykong15]

Hi,
I have recently purchased a set of epaulettes, which in believe date back to ww1 or earlier.
I have been told they may be a ww1 German generals.  However I cannot find any proof of this or any further information.
They have what I believe is the iron cross both on a little button and stitched onto the epaulettes.
The button has the following makers on reverse; "M.TILLEN & CO HOFLIEFERANTEN WIEN".

Any help at all would be brilliant! Many thanks
