I PICKED UP A LARGE COLLECTION FROM AN OLDER GENTLEMEN WHO WAS MOVING DOWN SOUTH AND DID NOT WANT TO HAUL SOME 1,500 INSULATORS . HE HAD BEEN COLLECTING FOR OVER 50 YEARS UNDER THE RADAR IF YOU WILL. HE HAD LOTS OF GREAT STORIES AND LOTS OF GLASS. I AM STILL IN THE MIDDLE OF GATHERING THEM ALL UP. THIS IS THE BEST INSULATOR OF THE BUNCH A DEAD MINT 110.6 NATIONAL "CORKSCREW". IT WILL TAKE A WHILE TO GO THROUGH ALL THAT GLASS. SOME OF IT WILL GO UP FOR SALE. JUST A HEADS UP. THANKS FOR LOOKING.......
