In the early 1980's, when the lines of Milord and Gentlemen in celluloid were discontinued and Omas introduced its first models in cotton resin, the top of the range was the Paragon model.
The model was named Paragon but this denomination was never engraved on the barrels of the pens. The earliest Paragons were numbered on the grip (although they were not a limited edition) and had " OMAS-557/F" engraved on the barrel. Later models show only "OMAS EXTRA" on the barrel.
They were fitted with 18 ct two tone nibs which were offered in a wide range of grades.
This pen is an early Paragon with the "OMAS 557/F" and the serial number engraved on the barrel.
