Mario Barth had, as one of the first private customers, a tailor-made 1/1 edition made by the Artisan Studio; the piece was seen in the studio before completion together with brass samples and contains a diamond in the form of the Montblanc star on the cap. The final version is in white gold, while the photo depicted on the Montblanc website apparently shows a master sample in yellow gold with a white-gold nib — a material combination that was not used in the final piece. Barth received his copy at a preferential price; subsequent individual editions are, according to statements from the manufactory, considerably more expensive.
