Although we are used to know Omas Gentlemens as celluloid piston filler from the 1960s and Omas Gentlemans as resin piston fillers of the 1980s, a few Gentlemen models in black resin exist.
They are probably transitional models which retain the old-time Gentlemen name, before it was definitely transformed into Gentleman.
This pen is one of those models, as it has the Gentlemen engraving on the barrel but is is made of black resin.
The nib is a very nice and highly performing Omas 585 (14 ct) nib which is very smooth and can offer a pleasant flexibility.
The pen is in superb aesthetic condition. Nib grade is EF.
