According to Gibson Customer Service, this is most likely a Gibson A- 40 or a A-50 mandolin from the 1950s. It’s been fully refinished so there aren’t enough telltale marks to get a full positive id. There are no identifying stickers or emblems on the guitar. This has been in my family for decades. Unfortunately, the original parts have disintegrated. They are included along with some replacement parts purchased. Will consider reasonable offers. Will ship to the continental USA only. No returns or refunds.
