Anyone else keep an eye open for old tools? I picked up an OLD circular saw for $20

I inherited a bunch of old tools from my dad when we had older family cars .Sears Craftsman Engine Analyzer for setting the dwell,tach,bad points,amps.A couple of old analog multimeters ,a timing light from Montgomery Wards (I remember him buying it in the late 70's)All still work to this day Wrenches and other tools from older USA tool makers like Plomb,Fleet,Proto ,Utica.I remember him using the Sears Engine Analyzer to tune our family car which was a 71 Duster with a slant 6.Shoot,I was brought home from the hospital in that Duster.I was born Mopar :D
I use that engine analyzer to this day on my Duster.
