When i saw it on a local for sale list my first thought was "what on Earth is this...? "
Fortunately it did not take too long to find the instruction manual, thanks Tektronix ! I recommend taking a look at it as it has full device specification and interesting information about type of measurements you do not do every day.

Nice find, I have personally never come across such unit. Looking at the heavily corroded PL-259/bnc connectors and associated coax cable, it seems like some fellow amateur radio operator found a practical application for this device

Nice! I think that's the second or third resistivity fixture Keithley made. I have the 8008 version on my desk that added a switch for volume measurements instead of requiring separate connectors.
The most recent version is the 8009 that made the connector plates spring loaded instead of screw-on.

Here's the wiring schematic for the 8008, I think it's especially interesting how the electrode connections change from surface to volume measurements. Like the ring electrode being guarded for volume measurements to prevent leakage to ground.

I could buy the poor guy to save its life but can't think of any use in my shack...

Cool, buy it! I'd let the seller keep the skanky cable though - it looks like something they fished out of a sewer!
