Rösler, J., & Wallrafen, S. (2014). Collectible Stars I: 1908 - 1947.
This pen was manufactured in Hamburg in c. 1930. It has the striking lapiz lazuli or lapis colour inspired by the semi-precious rock that is legendary for its intense blue colour with gold and white marbling. Collectible Star I rates the lapis No. 25 as a 10 out of 12 in rareness, described as a "once in a blue moon" find. The nib is a beautiful 18c with a flexible F point.
A few variants in clip designs have been found on the Meisterstück series. The teardrop clip on this pen is period correct and is one of my favourite designs.
