I have the opportunity to buy this french artillery tunic. the current owner is not to sure what model it is. Can’t find any history on the 19th artillery.

I am a ww1 collector and would love to have this in my collection, if its ww1 era. I know the french didn’t change their uniforms much from the 1870’s until 1915 or so I am unable to tell. to me it looks like the "Tunique Modele 1897" but then google images isn’t always good for comparison pictures.

And possible info on this would be greatly appreciated!!! Thanks.
