This one is listed as RARE by McKearin, but I think that it is more common than that... I would call it scarce. Anyways, it is the GII-72 "B" mold with the keyed base. Regardless of the scarcity of the mold, this is a GREAT example. VERY boldly embossed, and good color. Nice crude twists in the neck! I don't see any condition issues at all... a beauty!
