Hi all,
I just bought a vintage OMAS. It is black with gold trim, looks like a 555, piston fill but with no ink window. Greek key cap ring, no trim rings anywhere. It has no serial number imprint, but says "OMAS Extra" on the barrel with the stylised "S". The nib is lovely, fine and flexible. BUT I don't know what model it is. Closed it is 133 mm (5 1/4 inch), open it is 11.9 mm (4 5/8 inches). Barrel diameter is 11mm (Roughly 7/16 inch).
Any help much appreciated!
Thanks,
Ralf
