We don't see these in rosewood very often.

I have no connection with the store and have not seen the instrument in person.
The fretboard has a couple more dots than usual, and it has rounded corners at the end, rather than the usual extension; so it might have been modified or replaced.
Since these mandolins were made with bar frets that have often been ground down very low, that might not be a bad thing.
