A piece without a precious-metal imprint is no real vermeil (gilded silver) but merely gilded brass; even real solid-gold writing instruments always bear a corresponding hallmark (585 or 750). The absence of a serial number and the sole engraving Germany point to a model from the time before 1991, since Montblanc only introduced serial numbers from this year. It is therefore an older version of the Solitaire Korn in gilded brass. This information can be confirmed by the relevant Solitaire Vermeil Korn overview on fountainpen.de.
