I have a CD 143.5 with an issue......looks like an inclusion that appears to be a chunk of metal caused a section of glass to pop out leaving the inclusion present and a cool scar. There's a small bb hit to the top of the dome, but other than that it's in great shape. Asking $50 delivered to the lower 48 for this unique glass orb. I have a closeup shot of the area in question, just ask and I'll send it off to you. E-mail with any questions and thanks for looking. PayPal no fee accepted.
