AHAH!!! The dreaded five dot combination!!!
OK that makes sense, and works out by saving space.
With that in mind, I think of the dot combinations in the Italian blade markings. ….those 'Genoan' sickle marks while seen in pretty standard arrangement were often realigned in all sorts of configurations.
It truly is interesting to look into. A mark may have had peculiar significance in its origin, then later become looked at as a sign of quality......further copying led to its use as an aesthetic theme or arrangement...its original meaning long lost.
In Germany the use of Toledo markings were much in this manner, and certain marks were paired or grouped completely incongruently .
It all makes for interesting study and investigation for those who enjoy a good mystery.....weapons have a lot of 'em!!
