Weidenhoff Magnoscope

This antique magneto tester had just been used to test the rebuilt magneto for the antique Gibson tractor We had recently purchased... The guy who just rebuilt our tractor magneto (Marty) went through the whole setup and operation of this antique tester which is just amazing for old school electrical / mechanical engines... Todays engine's require computer chips and a laptop to run... This setup is becoming a lost art... So glad for the lesson today
