Good afternoon all, I need to have my Soverign Cornet looked at. The 2nd valve water spring has become slightly bent and has moved slightly to the side . It doesn't seem to affect the playing of the instrument and I don't get any leakage from it. However, I would like to get it fixed at some point (as my band will pick up the tab). Does anyone know any good brass repairers in the Sheffield area who could make this repair? Thanks all, Nick.
