popular ! Extremely rare & extremely attractive vintage Montblanc, name unknown, ballpoint pen

This is a ballpoint pen with a Montblanc hammer trigger mechanism. It was sold for a extremely short period as a set with the Montblanc 2209 fountain pen. While models with a resin lower barrel are common, the complete-metal, chrome-plated model is considered a rare item, even on overseas websites where its name is unknown.

Functionality has been confirmed.
A refill adapter and a black refill are included.
