I have an Alvarez banjo, apparently a Minstrel 5-String Model No. 4289, likely 1980’s/1990’s, with bow tie inlays that is in nice shape and plays well. Has the original hard case and tools. There is no model number or serial number I am aware of, or marked on the instrument, but see attached brochure. I am including a new DrumDial to adjust the head tension I have used once to replace the head. Feel free to email with questions.
