Here is one of the really tough HG widegrooves to get.HGCO /PATENT MAY 2 1893 EIN[O3O] in a Deep, dark olive with messes of light amber swirls. Very impressive insulator and shows backlighted in person much better. The contrast of dark VS bright backlighting kinda blinds my camera like an eclipse but you can see the amber in swirls and eddies inside the glass, especially closer to the dome. Exceptionally clean signal, usually these Pettos have the bases busted up pretty badly.3 drips are open bubbles,2 drips are slightly nipped and an almost completely invisible small ghost bruise at the side under 1893.There is also 1 small domeside peck and a few pin point fleebites. Displays VVVVNM from front and rear. Upgrading from this one will be quite the challenge! More photos on req. First mail to me.... $405 shipped in USA/CANADA, other countries I will assist with shipping. Well, let's give $335 a try.
