A couple years ago i picked up a tube from northern lights outside of Albany, NY. It resembles a recirc but i cant find any info on it or even a picture that resembles anything close to the piece. Any info about it would be appreciated like what series it is and if any others are out there, i have a couple friends intetrsted in buying one but i don't want to part with mine. Will try to upload pic later but on cell now, but it kind of looks like an hourglass with a sidebar that attaches the top and bottom chamber of the hourglass, an angled neck piece so no splash, when u first pull it bubbles up through the hourglass and when cleared the water pulls through the sidearm and flows back down through the hourglass. Any info would be greatly appreciated.
