Hi irbassist, like Eric says, those hatpegs and outside linings (there's a special name for these I forgot) and the general look of it seem like German bass to me. I have one myself that is supposed from the 1880s. Probably you will never know exactly what it is or how old it is, so if it sounds good, play it and fuh-get-abowdit. It looks like a nice bass to me.
But, if you want to do some research on the french versus german question, there is a bit of info on smithbassforums.com , see the thread on
german basses and the one on
french basses .
EDIT: the thread on
german shop basses might also be good since yours might be newer than previously thought.
