I wonder if she’s older than me
That would depend on how old you are.
I'm not a luthier, but
@Greg Clinkingbeard is, and I'd tend to believe his assessment. Whatever the age, it looks like a nice used flat back DB.
For fun though, I always look at tuners, not so much because they define the age of the instrument -- they don't -- but because their technology and condition does help define how old the tuners are, and because how they fit makes an interesting statement about the instrument...
The tuners on this instrument do not appear to be the original tuners. They don't match the pressure impression over at least one of the finishes in that area, from at least one generation of previous tuners. That would to me imply that this instrument has been around long enough to have had or needed some work at least in that area.
And that area where the tuners don't fit reveals what appears to be a thick over-coat of finish, more implication that there has been some work at least in that area.
Also, the tuners are of an antique "hat peg" nature, and since they aren't the original tuners, someone put them on this DB, probably either because they had them laying around, or because they preferred them. While not absolutely certain, that would imply to me that someone wanted an antique touch to this instrument.
None of these things identify value, but they do identify characteristics that may add up to a conclusion about age.
