This vintage instrument appears to be a Regal brand flatback mandolin from the 1920s or 1930s, featuring a distinctive "reverse scroll" shape on the upper body.It is a 8-string, oval-hole mandolin with a sunburst finish.

This beautiful item needs three things.

One string

Freight bar is loose

Tuning.

Other that that the mandolin has normal wear and tear on it. Varnish scraped off from playing. The case does has keys with it. I am asking a measly $400 on this gorgeous piece of history.
