Unknown Bowlback Mandolin (needs nut)

Listing this mandolin as "good" only because nut is broken and needs to be replaced. Otherwise this vintage bowl back mandolin is in" very good" condition. I see no cracks in the seams on the panels in the bowl, which is common with bowl backs this age. There is no label inside, no maker's mark of any kind so I can't determine maker. I'm guessing this is from between 1900 and 1920. Even with the nut broken, it still plays and sounds amazing. Comes with what appears to be the original case which is made of some form of canvas. As is the case with all my sales, this is an AS IS proposition. I do my best to accurately describe the instruments that I sell, but if you have any further questions, feel free to send them to me. Thanks and good luck to you.
