1921-early 1922 Gibson A-4 mandolin from the early days of the highly regarded Lloyd Loar Era at Gibson. This A-4 has an adjustable truss rod and adjustable bridge which helps confirm the date of manufacture. Serial number is visible on the manufacturers label. Mandolin plays very nicely and has a warm vintage tone. Tuners work smoothly and keep the mandolin in tune. Fretboard and frets show minor wear as expected. Body binding is intact. “Gibson“ engraved tailpiece. Patent stamps on pick guard, support arm and bridge base. Original case shows moderate wear but remains serviceable.
