As near as I can tell, this unit does not function. The crank is slightly bent but still turns the front roller. Included are six loose rollers loaded with paper songs. There is also a roller loaded in the machine. The box is solid and the hinges and lids/doors all work as they should. I am unable to ascertain the condition of the mechanism inside. The base of the unit measures 15 5/8 inches side to side, 13 3/8 inches front to back and 14 inches high at its highest point. The handle s...ticks out 3 3/8 inches from the box. There also is a photograph with the reed cover removed showing the reeds. On the right side of the roll is stamped “12780”.I am not an expert on this item and have described it to the best of my ability.
