Euro/French adapter for Gaslow bottle

Hi all,

I was going to tag my question onto another discussion about on board gas tanks/bottles but I though it would be missed.

Does anyone/has anyone got a filler adapter for Gaslow for France? 

I have looked on-line but they don't look right.  Can someone give me a part number? How do they fit into the fitting whatsit? 

Any help would be really appreciated 🤓
