AIR TWIST Martini Cocktail Mixer Pitcher

Hi everyone. This is a tall ... 13" at the lip/spout! ... martini/ cocktail pitcher with an AIR TWIST PEDESTAL STEM AT THE FOOT. I am stumped - who made it? - because I haven't been able to find even ONE other example WITHOUT A HANDLE! All the ones I've found have handles, even those made by Steuben. No mark on this one; has a polished 'pontil'. Have you seen this handle-less air twist pitcher before ... or can you identify the maker? Thanks!
