OMAS EXTRA 557 PISTON FILLER - 1946

At the end of WWII Omas rejuvenated its models and  introduced the piston as a new filing mechanism. Although Lucens and Extra Lucens plunger fillers remained available till the 1950's, they were flanked by a new line of piston fillers which were called Extra and numbered with 55X sequences. 

The new extra piston fillers retained the roller clip typical of the previous Extra models (lever fillers) and were produced in three sizes ( 555, 556 and 557). Known colors are jet black, brown tortoise, gray pearl, arco brown, arco gray, marbled blue and probably a few others.

In 1948 this line of pens was replaced by the new ogiva-shaped models with the same 55X model name.

Omas Extra piston fillers are therefore pretty rare due to their very limited time of production. 

They are fitted with Omas Extra 585 nibs and are fantastic writers, very robust and with a perfectly balanced size. 

This Omas Extra piston filler is an oversize 557 in black celluloid with a peculiar customization on the cap. The small logo in the shape of a soccer ball with numbers is the symbol of the Italian Totocalcio (the official betting system where you have to guess which of the two teams in a match wins or if they tie).

The pen is in excellent condition and it is a fantastic writer with a superb EF, very flexible nib.
