Featured I'd like to learn who this glass manufacturer is

French (I assume) two colour opaline vase 17cm height,7.5cm foot diameter, and 7cm mouth. Also what is the bowl shake called? Age? Mid-20th Century!

Mark looks a bit like a scorpion to me, although it might be different if rotated. I don't think I can improve on the photo.

Thanks for your help.

 

I see a butterfly. Lovely colour.

 

I don't believe that is a glass mark. More likely a cut & shut mark from where the glass was snipped off with shears. Best guess would be Portieux Vallerysthal

 

I don't see a maker's mark either. I see a 'haul me home' mark.

 

Not a makers mark, agreed.

Try Opalina Fiorentina. Empoli.

Thank you all for your help and encouragement. Didn't find the exact model, but some very close to it. I will give it to my niece when we visit the UK next week.
