This second edition is both simply written and clearly illustrated by a person who is both an experienced technical engineer as well as a concertina tinker. The topics covered range from fault-finding charts, basic examination and purchase advice through the common service and repair jobs and techniques to some of the more sensitive reed work. The manual has been considerably expanded from the first edition in both the breadth of topics covered as well as the depth of the coverage in each case. While always intended to meet the needs of players of all of the concertina systems, this edition goes out of its way to be as versatile as possible without sacrificing detail and usefulness. Whether intending to carry out running repairs, to service, to restore or just to know more about the innards of that strange and fascinating instrument, this Mally Publication will be an essential addition to the concertina players toolkit.
