I just picked up a Tenney Tone Edge from a music store in L.A. Its amazing, but I was hoping for a little more info on it. I was wondering about its age. Its not a slant, and it does say USA on it.it has a bp10e stamped on the back. its very worn, definitely not new. the box it came in was white with orange letters, says eburnated hard rubber mouthpiece on it. 2201 industrial parkway elkhart IN 46516. taped on was a tenney pro line woodwind mouthpieces sticker. 2810 neola ceder falls, IA 50613. Any info is appreciated!
