A 17th to early 18th century piece, this is hefty nicely balanced piece with a very servicable blade. It is made in a style reminiscent of earlier Italian swords. There are a few similar pieces in the San Marino Museum wth near-identical ball pommels and terminals to the guard. One of these examples even has a very similar blade with a distinct yelman.
Whilst optimistic I believe this is a 17th-18th century version of this sword rather than an original c1560 piece.
The sword overall has signs of wear with pitting to the guard and blade.
This sword could be yours for £995 or best offer.
