This is a fairly rare Washburn M-7s mandolin. Maybe made in Japan. Late70's 80's. It has a single transverse top brace,  Gibson oval hole, and has a wonderful tone. It is built of all solid woods: a carved spruce top, carved bird's eye maple back, maple sides and neck and ebony fingerboard. Serial Number is 2178.These mandolins were made for a short time in the early eighties? The model # is M-7S-N, M-7S-SB or M-7S-BR for natural, sunburst or brown. The S indicates solid top. I've seen these priced from around $600.Condition> has some marks, few scratches, some corrosion on end plate.SEE PICS. In the last pic see what looks like a repair between body and neck. Structure looks soundI have owned this for more than 20 years it was given to me but I'm not a mandolin player. I play Acoustic guitar. It has been stored in a hard case.The bridge pick up works, I have plugged in to an amp recently. Neck looks straight to me. There is some light fret wear to be seen.Any questions please ask and I will answer if I can otherwise nice mandolin and maybe a good restoration project.Shipping to lower 48 states only.
