You're quite welcome Jean-Marc! Looks like an extremely nice sword too, and most interesting interpretation of these markings. These kinds of variations are seen in numbers of other markings as well such as the 'anchor'; 'sickle marks'; and cross and orb which are some of the most familiar types.
The chart Dmitry has posted is from Eduard Wagner's "Cut & Thrust Weapons" (Prague, 1967) and well illustrates my point about the absence of linear developmental chronology with these markings, yet shows some of the variations. I believe these 'dated' examples are drawn from examples the author observed and the presumed period of the weapons he saw them on, as often the case in catalogued items. There are no regional classifications nor associated makers noted and essentially these are random examples of this commonly and widely duplicated image.
