In total accord with what Lee says, Ive sure made my share of misTEAKES !!
As you said earlier Serdar, it is in essence TUITION.
It seems that the practice of 'enhancing' old blades is one of the most common ploys used by charlatans that have long been around. The 'industry' of these kinds of fakes has been extant in Poland and some of these East European countries for decades. These swords are quite rare so it is understandable that copies made would be lucrative.
The inscriptions and inlay work can be seen in many of the esoteric books on these swords, but the application seems far too heavily added.
