Orange, curvy, and a barrel of fun

It has been suggested by those wiser than me that I should post pieces separately so here is the second of my recent finds I like to think of this as an end of the world champagne flute because being (I believe the technical term is) double waisted it has a larger than average volume and it's highly visible in an emergency situation so it seems ideally suited to the role. Anyway I love it but hopefully someone on here knows what it is and wants to share :-)

Could be Italian, could be Chinese. An interior picture might help.
