On the basis of an unsharp photo, a final judgement is difficult; the clip form of the 146 has slightly changed several times in the course of the decades, so deviating details do not necessarily indicate a counterfeit but can point to an older production period. As far as recognisable, the clip in the specific case appears plausible and fits a not-quite-current writing instrument. For a reliable judgement, a sharp, well-lit photo would be necessary, complemented by details like inner thread, serial number and nib engraving.
