This rock looks loose.

I found this gem on the curb in the bottom of a box of interesting electronic trash. The house it was in front of has a history of getting rid of some good stuff. I'd love to know what they deem too good to throw out. I took the meter home, along with a shelf and some other treasure, in the front of the orange bike's basket. Very Sanford & Son.

And it works! The battery had corroded, but it had fallen out of its holder before it spilled its guts, so all the corrosive bile was easily cleaned off the bakelite. It won't replace the fluke DMM, but it sure is nicer to look at.
