The inside of a concertina is jam-packed with little tiny moving metal parts with narrow tolerances, many of these subject to the shrinking and expansion of the surrounding wood due to changing environmental conditions, or prone to pieces of dirt lodging in small crevices. Annoying minor problems, such as sticking buttons, buttons lost under the keyboard, mushy action, slipping springs, buzzing, squeaking or silent reeds, etc., are a fact of life in the concertina world. It would be wise to learn to do your own repairs - most of these little twiddly problems are easily cured with a little mechanical ability, dexterity, care, and common sense.
