Battara, me too!!! Think we're gonna have a bunch of shorted out keyboards!!!
Jens,
That is most likely a Solingen trade blade, as they were typically using Spanish names and mottos at this time in the 18th century. It would be difficult to assign to a particular maker unless there was a key marking separate on the blade somewhere, but most of the time they only carried these spurious inscriptions. These blades seem to date from Solingen from latter 17th to early 18th century, and the Spanish name thing seems to account for a lot of the blades found on Scottish swords of this period too.
Even if we can match the name it is unlikely going to be that of the maker of the blade unfortunately.
This sword is incredible....centerfold material!!!
All the best,
Jim
