Hi Fernando,
it is a smallsword with a shortened rapier blade from the second half of the 17th century, which is used again 100 years later.
there is not Iohanes Portugal engraved (this makes no sense
) but
Iohanes Beugel a famous swordsmith from solingen in the second half of the 17thC. his mastermark was a Moors head.
best,
jasper
