If you are looking for a challenge, here is your pen.

Tabo was one of Italy's leading brands at mid 20th century. The STB was their second tier line, but with solid quality and beautiful celluloid.

This lovely little pen has issues. The ink window has separated from the body and the pen cannot be resacced until the window is repaired of replaced. So you get a great pen, either for show or as a project, for cheap. (IT4401)
