I've always found the listing of gear in one's signature line to be kind of interesting. I could own 25 exotic high end trumpets and flugelhorns, but it doesn't mean I can actually play well on any of it. It just means that I spend a lot of money on equipment. In my case, I don't spend a lot of money on equipment - I find a horn that works pretty well, and I use that. I'm also not into the vintage instrument craze, so I don't have anything out of the ordinary or interesting that anyone would actually care about.
I might add my antique 1886 Winchester rifle to my signature line. Unlike my trumpet equipment, that actually is something other than run of the mill - it's quite a special, rare bird indeed!
