found this little pocket DMM (oops, not a DMM, just a regular multimeter, lol) at my local shop, today (halted). looked interesting. I like old analog meters, especially cute little ones.
"how much for that triplett in the glass case?"
"don't know. no price on it."
(two salesguy discuss it amongst themselves)
"how about $10?"
"deal!"
dc volts is spot-on, and so is dc-current. the resistance ranges need 1 semi-normal battery (1.5v N cell) and a strange odd cell (15v cylinder cell, almost like a 12v 'security' battery). good that the odd cell is still available on amazon ($10) and that N cells are mostly easy to find. the N cell does all the R ranges except the 'x 1k' range, so at least it can do basic continuity with just the N.
it takes mini-banana jacks (which I don't have any of) but other than that, its one very cute little meter.
I was extremely surprised to find it still available, new! parts-express has it, as do others:
