I have a 1934 Elkhart Cavalier, essentially a Conn 4H. It has a trumpet-style water key. The original spring bit the dust halfway through jazz rehearsal this afternoon. Does anyone have specific recommendations for springs that will fit? I would rather not buy a bunch of different trumpet-style water key springs to figure it out.
