This is what probably would be considered "script" style or "Covington" embossing. Crude lettering; the G is shaped similarly as on the older "Petticoat" embossed H.G.CO. beehives. This may be the oldest mold variants of the "Non-Petticoat, H on dome" 145s. Lettering height is approximately 8 mm, with some variation from mold to mold.
