Cavalary Crusher Visor cap - help!!!

[Jerry B]

I have seen several fakes with the Prussian eagle mark on the cello. Also, the peak does not look of the epoch, either, as I have a number of caps with leather peaks.
Thirdly, the insignia does not look correct, either. That is, the patina on the alu wire.

Though on the first two points I can only agree with FB because it looks wrong, on the third point about the insignia and the stitching both look very bad, not period made or applied to my eyes and on this latter point I do have some knowledge.
