I purchased a Sterling euphonium from Custom about 2 years ago which was used as a demo horn. I believe this is a "symphony" model and has the "Perantucci" name engraved below the Sterling name.
I'm trying to update my instrument insurance policies and am attempting to locate the serial number. I've looked on the valve casings (all four) and a few other places with no luck. Am I looking in the wrong place? I should point out that my vision is not the sharpest but I have used a magnifying lens to help me.
If anyone knows where I should look, please let me know.
Thanks
