Simpson Model 260 Set Tester
The Simpson 260 VOM is probably the most common analog Volt-Ohm-Meter used in industry since the 1950s and is still manufactured and used today.
This Simpson 260 pictured was my first piece of test equipment. I've owned it for over 48 years and during that time have blown it up on more than one occasion.
