Does anyone have a number or a name of the company that makes the pocket size, aluminum center conductor size guide? I have one, and on the front it has the name "JUMPER" and half a phone number, (925) 44_ - _11_ the rest has been conveniently rubbed off through usage. I was hoping someone might have the rest of the numbers, or at least some of them to cut down on the amount of wrong numbers I am about to start dialing. Thanks
