Check out what I just found for $8 at a local Electronics recycler!
A Dekabox DB-655. 1R to 2MR (-1R) in 1R increments! Even has a calibration sticker on it from a General Dynamics Aerospace Standards Lab on it from February of 1965! Though, can't say I know what you'd calibrate on something like this...
Seems like it's in great shape. Anyone have one of these? Know if I should open it up and clean it out or anything? I'm actually curious how they're set up... I'm guessing they're set up as a Kelvin-Varley, but I can't say for sure.
Still, pretty sweet for $8!
