Sabre of revolution period. Dutch cutlass 1780 type?

This saber was exchanged to us by a customer as being a revolutionary Montmorency saber.
The reduced length of the saber, the summary mount, gives it an appearance quite close to the revolutionary productions that were extremely various.
On the other hand, the assembly of the guard branch, which is fixed to the base of the cap using a screw, is not at all in the style of French productions.
The model rather resembles Dutch boarding sabers of the same period. We found on French boats of the time, but also in infantry and cavalry, war spoils from all over Europe, even foreign blades mounted on very French hilts, or the opposite.
This saber is probably not a 100% "made in France" production, but is all the more interesting, especially for collectors on the maritime theme.
Length 820 mm, including blade 695 mm. No particular marking. Global good condition. One hilt bar is cracked, but nothing is lacking
