The Omas Extra Ogiva piston filler was introduced in1948 and remained in production for a very short span of time.

It was an innovative model but it was soon replaced by the 55X series, very similar in design but with a more slender look. The two lines, the Extra Ogiva and the 55X are actually very similar.

Omas Ogiva Extras were produced in three sizes: lady, standard and oversize. Even after the introduction of the 55X series, the Ogiva Extra oversize ( 557) remained in production with very limited variations in style and design and continued to be identified with the Extra name.
