Tibaldi Firenze PERFECTA

A very rare version of a safetyfiller pen.

Here is a very rare version of a safety filler pen made by Tibaldi. It takes some time to understand how this pen works.

Unscrewing the cap, the nib snaps out - being pushed out by a spring.

Screwing back the cap, there is a silver pin inside the cap, that pushes back the nib against the force of the spring.

Now, with the cap in hands and the nib out - this is a safetyfiller pen, how to get the nib back to fill the barrel by means of an eyedropper?

The solution is a tiny clamp, like a collet of a drill,  at the barrel end. - The thin hard rubber rod inside the pen rests inside this collet.

Now, with the cap screwed onto the barrel, and the rod pushed back you have to screw out the small turning knob - this pulls back the collet till it tightly holds the rod.

Now you can unscrew the cap with the nib remaining inside. The pen is ready to be filled.
