Interesting grenadier briquet for comment

[Valjhun]

Hi,

At a militaria show, I saw that briquet wich intrigues me. At first sight seems like a frenc 1790 model, but Im not certain. The hild is more slender than the typical french grenadier swords.

Wich is very interesing and quite unique is the blade. Deep fuller with engravings and inscriptions on both sides. An briquet rehilted with a shortened hussar blade? Would that be the case?

Can anyone tell more about it?
