It is an OPW tri-set timer.In the days when gas prices were in the 20 to 30 cent range you could set it at one of the stops and set nozzle at low speed and it would cut off close to what ever amount you timed the stops for,this way you could check oil clean windows ect.Then you could round it up the dollar amount the customer ask for.Very rare only one I know of,it was NOS.The have the box and instructions.
