Need help identifying a shell casing-French 75mm

I have been given a shell casing by a friend who did not want it and I am not sure what type could someone please help me with identifying it. I have put a link to the image.

David, welcome here.
Your case is a French 75mm for the field gun. Made in 1916.

Hi do you know anyone selling a shell that would match the casing

Actually not but I guess in France they could be available.
