Interesting site though, ran across this
To me this seems very close to my instrument, I think they are calling it a Derazet. Not a maker that I have ever heard of before. Does any know anything about this maker? I have to admit that with French instruments there are so many subtle details that you have to pick out making it rather hard to pin down an instrument by an unknown maker, even it if is a bit odd like mine.
Even this one makes me think of my bass in a way, at least if it had violin corners
