RADIUS SUPERIOR red arco ogiva

Radius Superior in red arco celluloid from the late 1940s. The pen is not marked Radius on the barrel but has an advertizing " Società Italiana Navigazione" ( Italian Navigation Company) .
This kind of customization is pretty common on Radius pens and on many other Italian brands of the 1930's and 1940's
The nib is very smooth and flexible.
It is a sturdy pen, suitable for everyday use and highly collectible too.
