For all you die hard CD 134 pennycuick collectors here is an insulator you don't often see. The huge open interior bubble engulfs the whole dome above the threading. You can still see the pennycuick dot above the threading but it's off center. WOW! The only damage is a shallow pinky nail bruise on the lower wire ridge. $125 which includes shipping. PayPal as a friend of the family is the preferred payment method.
