French kepi ww1

[Helmcollector]

hello,
I must admit that I should have been more informed before I purchased this French kepi, as I am above all someone who collects helmets, but this kepi is a beautifull item for display in my collection.
I looked on the internet for the fabricant that you can see on the inside of the kepi, but little I could find.
Can someone give me more information about this French kepi ? Was it worn by soldiers or someone higher in rank ?
Thanks in advance !

Kepi is for rank of sous-lieutenant, 103rd Infantry Regt., period late WWI into WWII ( I think, kepis can be hard to date).
