Arrow in Scroll makers mark?

[Radboud]

Hello, I have recently aquired this French grenadier officers sabre dating to about 1788 and 1800. It's loosely in the petite montmorency style despite having an unfullered blade (the 'montmorency' moniker is a late 19th century collectors term, with all the associated flaws that come with it).





It's a fairly plain sword, as far as swords of this style go, but the blade has the flaming bomb emblem to match the guard, which is a nice touch.





But what I'm intrigued about is this scroll pierced by an arrow mark on the blades' spine. I believe it is the makers' mark and I'm sure I've seen it before, but for the life of me I can't find a reference for it in my books. Has anyone else seen this mark before?
