if you have a typical cerveny CC, the 4th valve tubing can be easily extended. I have a set of extenders I treid as an experiment to try to get a true chromatic down to Db. It worked to a degree, but I never use them anyway. Just get some inner and outer tubing, and go to town. no soldering required. Also, check the existing tubing for dents. the 4th valve tubing on those horns are prone to dents because of exposure, so I built a bumper guard on mine. E-mail me for pictures of both projects.
Also, if memory serves, David Wilson told me once of several Cerveny's that had a 4th valves that were equivilent to a 2-3 fingering. Maybe you have one of those. If the rest of the horn plays well, the 4th valve is easy to fix.
