The left insulator has a hand logo and G.P.O. (General Post Office) incised on it. I believe it is from Ireland. Has a recessed inner skirt. Next insulator is British, incised with the logo of Gaskell and Grocett. On the top it is marked 3/63. Has an extended inner skirt. Next insulator in incised L.M.S. on the crown and with some detailed markings on the unglazed top. This insulator has a recessed inner skirt. The last insulator (brown glaze) is marked G.P.O. on the top and has an extended inner skirt.

All are undamaged in excellent condition. The threaded pinholes are a small size and will not fit an American sized pin.

Asking $20 for all four. These are heavy but that doesn't matter since they will all be shipped together in a flat rate Priority Mail box for $13.60. Grand total $33.60. PayPal works best but will accept other forms or payment.
