Is this jug Norman glass? Also how to date?

Hello ! Got a little head scratcher (for me anyway!) with this green glass pitcher collected in France. It's in great condition, has a pontil mark on the base, and I think the handle is hollow. I am truing to identify the style and approx. age of this piece - have seen similar twisted ribs on Normandy glass but nothing in this colour, all shades of blue and clear, but nothing green. Reverse image search doesn't bring up any exact matches either.

The pinched spout and form looked mid century to my eyes, but the twist and handle seems to point a bit older, and Norman. But can't find anything in this colour.

So I'm well and truly stuck now  Any advice appreciated!
