Default Oldest piece of working and still used test equipment ?
I built a clock some years ago with the oldest components I could
find. Not exactly test equipment but it does meter the time
It is documented he

It uses some digital 74xx ICs from around 1972, a selenium rectifier
and of course nixies for display.
