I'm just putting this up to the top in case someone comes by who knows. I've looked into all the possible leads and found nothing. From the looks of the patch, I'd say it's around the WWI era, or a bit earlier.
In my opinion it's a hat badge and not a breast badge.
Looks like some italian hat bullion badges... Hard to find!
It is sure that it is not italian, i never saw before, all italian eagles from 1922 to 1945 has fascio with eagle. Before fascism eagles has a cross in the center like insignia savoia family
all is possible but for that i know also libyan volunteers weared a badge with 'fascio' (http://worthopedia.s3.amazonaws.com/...b436e8614a.jpg)
I 'll post the eagle in a italian forum and try to discover something
this is typically fascist eagle used until 1945.
Now after posted on italian forum, i can say for sure that is not an italian badge.
It' probably hand made fron 1920 until 1945, a friends found of badge is tryng to search something about the its origin.
the key to discover the 'mistery' probably stay in the center of the eagled, where a plant is represented, many african nations have a plant as national symbol.
i'll give you news as soon as possible
