Which model is a Montblanc ballpoint that is merely marked with "Mont Blanc - Germany" and bears no further type information?

It is a ballpoint from the Montblanc Slim Line or SL series, recognisable by the plastic logo in the clip; not from the Noblesse range, as a frequently cited book wrongly states. The new price was then below ten DM; the model is therefore no high-quality collector's piece but is suitable as an everyday-suitable writing instrument. It can be difficult to still procure matching ballpoint refills. In literature and on relevant websites, Noblesse and SlimLine are repeatedly confused, so source statements are critically to be checked.
