Do you mean 'dripstick? I believe the DC-6 came with 'dripsticks' that came out of the bottom of the wings at each tank to easily measure fuel levels and mechanics hated it 'OOOOOH evil!! Bad JuJu' but ,when it turned up years later on the DC-10, mechanics thought it was better than an empty gripes page in the log books.
It's a curiosity item now and good for asking 'so..what's this..?'
