Figure all Cs to have a tenor type neck except Conns from after about 1919. On a Conn or Pan-American, it will have a C above the serial number. The bell on some Cs is smaller. The only sure way is to ask for a measurement of the body WITHOUT the neck. An alto will be about 22", C Melody 24-26" and a Tenor 28+". If buying on ebay, ask before bidding. I just bid on a nice one that appeared to be a C but turned out to be a Tenor. I bid as if it was a C to protect myself. Stange thing though, 3 years ago a C Melody was a wall hanger and worth less than $100 and now some brands sell for more than an alto.
