Smallsword Info (named Sebastian Ernandes)

[RogerFox]

Hello everyone fellows. I'm a mail armor collector and restorer, but i recently bought a very nice smallsword. I would like your knowledge to learn a bit more about it... if possible

As you can see on the blade with the triple fuller there is an inscription XX Sabastian X Ernandes XX. I know that probably is a "fake" name as they used to make for make more valuable the blade itself... but you can also see the "anchor" mark at the end of the fuller.

The hilt is quite interesting, couse it looks composed in different periods, plus the (arch guard, i don't know the name) is made by movable pieces and not from a single molded one as usual.

Any tought about this piece that can help me identify it? Thank you very much.
