Mine is my latest find, a Simpson 269 series 2
100,000 Ohms per volt DC
5,000 Ohms per volt AC

WoooWoooo those meters look very familiar. Oh yea - calibrated many of those when i was in the Air Force. Great meters!!
Had a Triplett 60 for decades. George gave me a 260-8P last year because the guy he works for was done with it and it has battery mess inside. I had to clean it up, use the 9V retaining clip to replace the D-cell terminal and get inside and clean a board. Pulled a couple resistors to make sure it was clean. Then I built a battery cover for it and I have a fully functioning 260. Nice meter, my favorite Simpson for sure. Finding spare parts is expensive from Simpson.

Simpson 260. I have two of them and they still work great. Just recently replaced the higher volt batt for high resistance readings - that wasn't cheap!
They all get regular use.
One is a 260-4. It has a 5kV scale, useful for the ham radio gear.
Another is a 260-6M. The mirror scale allows more precise readings.
Another one is a 260-6P. The built-in breaker saves it when you accidentally connect to a live circuit while set for Ohms or mA ranges.
...the roll-up door. I also have the Transistor 'beta' tester adapter. There was an audio watt meter adapter offered; that one I would like to find even though it is probably mono.
I had one of those audio wattmeters. It was nothing more than a low-powered dummy load, with a slide rule attached to calculate wattge from AC voltage measurements.
Like it wasn't bad enough spending a week in blistering heat and a few thousand dollars. And then he takes my only vintage Simpson meter.
I don't want the lubricant to be oily, so I was thinking of using silicone spray. I haven't tried it yet, and I just leave the door open. I figured someone here would have experience with this. Thanks.
Sprayed onto a Q-tip, or brush, of course, and then swab the track.
I picked up a Simpson 260 from a railroad co-worker, when he retired in 1994.
Last winter I picked up a Simpson 260. Hardly used, a collection of leads and with a soft case. Most people don't realize the value of an analog meter.
