Concert Roller Organ + 3 Cobbs. It is in nice shape but I can’t figure out why it don’t make sound. The crank turns the cob and the keys go up and down, but I cannot get any noise. It can’t be too hard to fix. The unit measures 18.5 x 15 x 12 and weighs 16 pounds. See my other listings. For more great items! Txzj pxzj14877 txzj-11 txzj113.
