It's a very small bass; upper bouts are 19.5", lower are 26", body length is 42", Ribs are 8" at their deepest. It's selling as early 19th century French. The only bass from this time period I've ever really heard of is the Karr-Koussevitzky bass, which is actually fairly similar in pattern and size to this instrument. For reference:
