Help to identify a sword

[Almonzo]

I forgot to write that when I received the sword
It was very rusty and I cleaned it with a lot of baking soda.
I wanted it shiny but maybe it is too much and help to make it seems too "clean'/fake


I found , thank you ,
this 16th large cinquedea sword who don't looks older, guard is +/- look like
The pommel is as unusual as my wheel medieval pommel.
Maybe this one is recent too ?

I wonder if there are old steel leaf blades for comparison ,
The ones I found were all bronze made,
Sure iron/ steel avoid humidity and turn to rust then dust
but it is srange that since antiquity,, laTène period.
no celtics or just leaf blades steel models have been kept with care.
