LOL thrift store score "Bell Systems" / Simpson 260

I got a Fluke TS-100 that shoot cable distances to 3000 feet, pretty cool that you can program the values of different cable (coax, RG-59, RG-6, 24G UTP, etc. maybe even 14g electrical wire in a car? Gets opens and shorts down to the foot)

But the Onex 580 does this too: it's an all in one telecom meter, even draws dial tone.
