I've had my Selmer Mark VI tenor saxophone since I was about 15 (I bought it used sometime in the early 80's). It has a bit of road rash and is perhaps a little worse for wear, but it fits me like a glove (or maybe an old pair of underwear). I would be devastated if anything were to happen to it. It's like an old and dear friend.
I also have an antique guitar which I recently had restored to playable condition. It belonged to a lifelong friend of my father's. Dad bought it for $3.00 at his friends retirement auction sale when I was a kid, and it sat in the basement for a number of years until my mother threatened to throw it out if I didn't get it out of her way.
Check out the cool tuning peg.
