Thanks! I need to get proper lighting to get better photos, this piece does not look amateur off camera. It's a very well done piece I'll see if I can get better lighting for pics, The double barrel- is just more like a spiral , or a spiral staircase...spins all the way down ( I doubt they were going for a D Helix were they would have connector sections all the way down,,so there's two holes instead of one and the neck is fluted and curved, which was done on purpose for looks, which is was I think it's some sort of Studio Art glass piece , with a murano touch....still trying ti find proper ID /artist based on signature.
none the less thank you for the useful information .
