Xavier Jaquet ?

[Charles Federle]

When I first bought this bass it was advertised as a 1746 Mougenout. That idea has been dismissed, but now it is though of as possible an Xavier Jacquet or at least that school of making. I am curious to see what opinions everyone else has on it. Without a label it has been a bit of a mystery bass but I have considered myself lucky to have it.
