HP 85032B Type N calibration kit for refurbishment, almost complete. It is only missing the end cap on the tube that holds the inner extender that extends the plug inner when the N socket open is in place for calibration.  Most likely I can find a suitable end cap before the auction ends. The sticker on the box says that it is calibrated until April but this is not really the case. This is because only about half the components are from the same original kit. 

I have cleaned up the components a bit and they all seem to be within their specifications within the limitations of what I can measure. The female load is a bit better than the male load above 14GHz but still within the specification I think. In the plot the green trace is the male load, the red trace is the female load and the blue lines are the specifications for these. The female load in the kit is not the same one as in the photo, I have swapped it for a better one. The plots were done by calibrating the network analyser with another one of these kits then measuring this kit. Whilst the kits are only specified to 6GHz the results seem OK to 20GHz.  

The box is in mediocre condition and the latch is a bit wonky. There are some stickers on the box that I didn't think I could remove without damaging it too much but I gave it a go and they are now gone. The foam is starting to go off as it almost always is with kits this old but is better than most I have seen. I can include a floppy with the kit User Guide and the CK_ file for use in network analysers. 

Local pickup from near Camberwell Junction, VIC. Prepayment is OK or leave the money under the mat. Postage would be about $25 to anywhere in Australia including tracking.
