5 fishtail Hewlett suspension / strain insulators. These are not the really big full sized disks. The one in the middle is 7 inches diameter. The other 4 are the 6 inch diameter. Each one is a little different. One is a Hewlett 37. Others have the Sept 15 14 Patent date with either the serif font or sans serif font with different code letters. Glaze colors vary a bit as well. I think I can fit all 5 in a large flat rate box to keep the shipping fixed and reasonable for a quantity of five. $5.00 each. I will break up the 5 and offer just the quantity needed. First email as always! PayPal welcomed.
