At Aurora, the nib width is usually not stated on the nib itself but in some versions on the feed; from the imprints mentioned (14 K / 585 / Aurora / *5 T VO), the width can therefore not be unambiguously derived. Here, a query to the seller or a check of the feed helps most. Aurora nibs are basically regarded as well everyday-suitable, although especially elastic, obliquely ground nibs (e.g. OM) are rarer in the range and should be specifically sought.
