Incredible gold filled Parker ?Lucky Lock? mechanical pencil. This pencil was made in the mid 1920s and features all the expected qualities: light etched design, gold filled coloring, wide lettering on the Parker logo. It is tagged AT-SEP at the top of the clip so I believe this to be an earlier model of an already rare pencil. The gold has worn a bit but much of it still shines! See all photos as the pencil seen is the pencil received. More rare pens and pencils in our store! Shipped via USPS Ac Antique Rare PARKER "LUCKY LOCK" Gold Filled Ring-top Pencil Made in USA AT-SEP.
