PLEASE READ BELOW INFO I GOT FROM A VIEWER:
Your photos are of a NRI 66 tester (same circuit/design as Triplett model 2413), made by Triplett. But your description does not mention that its panel meter had been replaced with a Simpson 1mA-DC panel meter; probably because its original Triplett panel meter had been broken or lost.
The NRI model 66 is the same as a (later) Triplett model 3413. Design-wise Triplett models 2413 vs 3413 (NRI 66 vs 67 thru 69) are completely different in the wiring scheme to their 3-position (ten of these switches; labeled Down-Center-Up) switches, making their instruction sheets and tube charts completely different from each other. Buyer beware, I guess, as this definitely doesn't merit nearly the price you've asked, imo. And these NRI models are not rare. Fred, Triplett collector since 1958; originally of Bluffton, Ohio
