Update - no reply to my emails sent to the address Nick gave.
Interestingly for me, it turns out that my German bow, on loan to me from a friend, is also the same brand.
My teacher looked at this French bow, played it, and told me it was fine for me. His comment was that I could probably pay $500 and not end up with a better bow than this one, so I will stick with it for now, its mysterious origins not withstanding.
