Here is an insulator that I am most certain to regret selling, but here goes! One of a kind ice blue aqua Whitall Tatum CD 154 with a HUGE thumbnail sized bubble in the wire groove. When it came to WT quality, they, like Hemingray had some of the strictest standards. Very few WT insulators have any kind of noticeable sized bubbles in them bigger than a pencil lead, and certainly a bubble this size will probably not be found again in the near future. So, if you like junk in glass insulators or are the big bubble specialist, don't let this one out of your sights! Insulator is dead mint condition. $68 delivered. Ok, I am gonna knock this down just a little bit. When will one of these come available again? $37 + $7.50 shipping. delivered.
