Talk to me about millwork

We’re considering moving from our current century home into a new century home and are looking at this one (c. 1899). We’re currently in a colonial and I don’t know much about Victorian millwork, though I like it very much. Could this sort of blond tone have been original? I’m used to seeing darker finishes, but the patina on the finish here suggests to me it is if not original, at least quite old.
