Most of us owning clockspring action rotary valves never want to see these springs. And I never have seen such a spring "live" through my 43 years with brasses.
So I cannot avoid taking the chance to show a pic of an old Czech bass flugelhorn with a broken spring casing.
All of the pics can be seen via the link given below here (Yahoo identity = brassphotos, codeword = public).
