This is a 1930s - 1940s Blue Comet "resonator" mandolin, likely made by Regal. The distinguishing features include a faux-resonator rim with side ports and a mahogany body.
Normal wear for its age. The instrument needs new strings. The tuning keys are tight, and may need oil or some other means to loosen them up a bit.
