This insulator I am not sure how to to call, it has the early HG PETTI style embossing in very faint script, but has an H on the dome and no PETTICOAT on the rear.99% of these H domers are prismic or stamped type embossing, so this one has kinda thrown me for a loop. Colour is a nice even blue and condition is VVNM.Colour in pic is accurate. $7 + $7.50 shipping.
