Swan SF1 ebonite pen, lever filler. It has got a great nib, F-1.9mm flex. Imprints not very clear but readable, scratches free, jet black. There was some plating loss on the band, I treated it with a Sunshine polishing cloth but it will most probably show up again (the action may be repeated then). The lever shows some wear. The pen measures 13cm closed, 15.8 cm posted. It has been deoxidised, polished and protected from oxidation.
