This CD 376.2 insulator has a Amethyst top and marked FIDENZA 6315. It is located in Australia and is available for sale to US buyers. The only problem i can find with it is the filler holding the parts together is loose and allows a little rotation of the top and middle skirts on each other. The insulator book price is $USD400 to 500. I am asking $USD350.00 plus postage. For any questions please contact me.
