Into the ether
The reason I am curious on the marks in the linear sequence on the blade rather than the usual makers name is they might have more esoteric meaning. Whether authentic or spuriously applied by German smiths,these are remarkably similar to some Milanese makers marks as well as some of the 'anchor' marks used by Toledo makers (i.e. Alonso Perez, late 16th, et al).
The others resemble some occult/magic markings which were often used in inscriptions, names etc. on blades by Toledo smiths (Wagner, 1967).
The Spanish method of swordplay was the mysterious system of 'destreza' or'the' Spanish Fight', (Aylward, 1945; Castle, 1885) which was based on geometric, mathematical, philosophical and occult principles. The weapon of choice was of course, the rapier, and while in the earlier years, very long blades were de riguer, however in time 'shorter' blades became favored (i.e. these 37" examples).
I think it may be possible that a series of marks similar to established ones used in Milan and Toledo on blades, coupled with magic type sigils might allude to a swordsmans knowledge and skills in destreza, and may have been applied in these sequences suggesting such esoteric connection.
Just thoughts.
