Rare 70s-80s Vintage Cross Century Made in USA Engraved, Writes

【Overview & Usage Frequency】
This is a rare vintage oil-based ballpoint pen from CROSS's iconic Classic Century model, manufactured between the 1970s and 1980s.
I am selling it to organize my collection. This pen is attractive for its solid craftsmanship and the substantial feel of the metal, which are not found in current models.

【Condition & Specifications Unique to Vintage Items】
The most notable feature is the clearly engraved **CROSS MADE IN U.S.A.** mark below the conical top of the pen, signifying it is an original American-made item from that era (see image). Additionally, the clip logo features the classic, vertically oriented font that was limited to that period.
While there are minor scuffs due to age, there are no noticeable dents, deep scratches, or plating peeling. Considering its age, it retains a very beautiful luster. The twist mechanism of the barrel also operates smoothly and is in good condition.
*Currently writes smoothly (ink level is unknown).
