Here is my attempt at a Conn trombone recognition guide. I admit that I am less adept at spotting the differences between Conn trombones. Consequently, this is only a general guide covering mostly instruments of 1945 and later. There are three approaches to figuring out what model an instrument is. The first is through the serial number and either the model number stamped on the instrument or the model name engraved on this instrument. The second approach is to look at the features of the instrument. I will first deal with recognizing a model through names and numbers. If you don't know or can't tell the name and numbers on an instrument, scroll down to the section titled Recognizing an instrument by its features. Thirdly, I give a list of which trombones have what bell size (have your tape measure ready! For the metric readers: an inch is 2,54 centimeters, and as usual European commas are American periods for decimal calculations). Recognizing an instrument through names and numbers The very first thing you need to do is to check and look up the serial number. On Conn trombones I believe(!) that the serial number is stamped near where the slide and bell sections are joined. Check the number stamped there against the Conn brass serial number list. This should tell you what year the instrument was built. Note that serial numbers on Pan American models don't match Conn serial numbers. The next thing to do is to check for model names or numbers. For a period from the mid 1920's through to the mid-1950's Conn stamped the model number right above or below the serial number, where the bell and slide sections come together. If you see a model number there (such as 1 2 H you are home free. Else check if there is a name engraved on either the side of the mouthpiece receiver/leadpipe or the bell. Check that name against the list below, which also gives some distinguishing.
