Speaking of Conn Connstellations.....My 1968 model (L-series serial number) now has both the bell front and the upright bell and cases for each. I was able to score a somewhat bent but serviceable upright bell off of eBay for my 24I along with a case to match. I just dropped off the horn with straight bell at Osmun Music to get the dents and creases in the bell straightened. So I guess now I can say that I have a 24I/25I convertible Connstellation. Also, last summer, I got the valves redone with teflon guides and synthetic felts. Valve action is now great!
