WW1 Brass shell case - please help to identify - General Ammunition Discussion - International Ammunition Association Web Forum

I found this brass shell casing at a thrift store and was drawn to it. My son, daughter-in-law and my daughter’s boyfriend all serve in the CAF. I would really appreciate help in identifying the shell casing marks on the bottom. I have read quite a few online so believe it is French made or made for France, it is from 1916 and that is about it. It is 13.5” tall and 3” in diameter. The only markings are on the bottom. I am including a picture of the markings. Thank you in advance for any as
