Up for you consideration here is a B / B in the EIN: 020 I'm going to call this a gray or off clear with a slight purple tint in the dome. Picture was taken using a 5000k bulb. Condition is VNM with the only issue being a very shallow 1/4" flake missing from the base and a shallow 1/4" bruise on the inner skirt. Take this insulator shipped to your door anywhere in the lower 48 for $23. More pictures available upon request. I take PayPal (gift mode), personal checks & money orders.
