Hi Fernando,
It is a French pattern for France.
Chistian Aries shows these swords in Volume one.
I have not translated the text but the specific subject heading is;
Sabre de la premiere compagnie des mousquetaires
premiere restauration troupe & officer.
Or in English
Sword of the first company of musketeers
first officer & restoration company.
This may also help.
https://en.wikipedia.org/wiki/Musketeers_of_the_Guard
This is also a great help in understanding the swords;
