Here is an average insulator embossed with a "B" and backward 10 on the dome. Its a Greeny color with Amber stringers throughout the insulator, and a piece of fire brick. Unfortunately my camera couldn't capture a lot of the amber. Almost mint with just a small chip on the lower wire ridge at back. Asking $12.00 U.S. + shipping. I prefer Pink International Postal money orders and cheques, but if you wish to use PayPal add $1.00.
