Without high-quality detail pictures, the difference cannot be unambiguously explained; one possibility is that the cap on one of the pencils is missing, which on some models makes the star appear removed. There are actually Montblanc pencils (e.g. of hard rubber, with cap) on which the body itself bears no star. The DB pencils are with about 8 cm length very small and presumably designed for address or notebooks. A final judgement requires the writing instrument in hand, since photos often do not adequately reproduce such details.
