VINTAGE ANTIQUE SERVO TEK SPEEDVOLTER VOLTAGE TESTER

Description

For your bidding pleasure here is a vintage Servo-Tek SpeedVolter from an estate. I really have no idea what this does other than maybe ohm/voltage tester but appears to be automotive orientated. I'm really not sure of it's exact value but nearest thing I could compare it to was on another auction site for crazy money but am starting the buy now price way below that. If anyone has any input please contact me. Thanks for looking and good luck
