The 2340 is the 3 valve and the 2341 is the 4 valve version of the same horn. King uses the designations UB for upright bell and BF for bell front, so the model number for a 4 valve bell front King would be 2341BF.
I have a Conn 21J that I use my 20K sousaphone bell on for outdoors. It really helps get a big sound. It's just a little hard to see around, but I guess it will do until I get a tuba bell for it.
