OMAS EXTRA 557 OVERSIZE- 1946 PISTON FILLER

At the end of WWII, Omas introduced the piston filling mechanism, which promised to be easier to use than the traditional plunger filling mechanism omas had used since the 1930's for the Lucens and the Extra Lucens series.

The new line of piston fillers was called Extra and was identified by a model number which was 555 ( lady size), 556 ( senior size), 557 ( oversize).

This Omas Extra piston filler is a 557 oversize in excellent condition wth a nicely flexible Omas Extra 14 ct gold nib.
