The Simpson 260 Series 3 arrived about 1959. Two versions were made, the Series 3 & 3A.

This model takes the banana jack type test leads.

The inside of this unit has a date stamp of February 12, 1959.

The same meter face as the Series 2A, with the addition of a number someone wrote on it.

Controls include: Ohms zero adjustment, AC - DC - Output, a 12 position Function / Range

selector switch, and we are now up to eight recessed probe jacks. 

The back of the case now has an "adapter lock" for use with add-on accessories such as the 625

temperature adaptor. The inside view shows the printed circuit boards have arrived and trim pots

for calibration are available. The batteries can now be installed without taking the whole

unit apart, only the back of the case needs to be removed.
