May I mention, that Seydel has its official repair method here http://www.seydel1847.de/epages/Seydel.sf/?ObjectID=25208&Locale=en_GB
It includes a toolset and the possibility to get single reeds as well as reedsets for both Diatonic and Chromatic Harmonicas. We also will provide single windsafers as well as whole sets for the Chromatic Harmonica and the special glue.
