Welcome to the forums
Cinellis pop up on the largest Dutch classified quite regularly. Maybe 5-10 on yearly basis. Mostly a Rampachino in orange or greyish/black. They look quite similar. More or less same specs: steel, racy, STX, same cockpit, graphics alike, painted to match suspension fork...
On that forks: It looks quite a lot like the fork I had on a well used Chesini. It said "REG" and "Made in Italy". Unfortunately the crown split when removing the Euclid headset race.
Relatively seen they are quite rare, but it is not like finding a Cinelli Super Corsa roadbike. They are not really high end, but more middle of the road, mid range instead.
