Conn Baritone and Euphonium recognition guide
Here is a little table I made to help me identify Conn baritones and euphoniums based on the bell and valve configuration. I think I have most models in there. The table could of course be expanded, for example by including the position (up or front) of the small bell on double bell instruments.
