Renishaw TS27R Toolsetting probe

I've been wanting a tool setting probe for my mill for a while now. It makes changing tooling a no brainer and also allows for high accuracy. These things are expensive however, so I watch eBay. After over a year of waiting, one came up for sale for $80. I went for it in spite of 3 strikes against the eBay add -

1. Crummy pictures - I almost never bid on anything that doesn't have good enough pics to show the details. 
2. Description indicated it was for parts as condition was unknown. 
3. Perhaps the biggest red flag - the seller was in Russia

But at $80, I was willing to take the chance. It turned out the seller was very responsive and great to do business with despite the obvious language barriers. Although, it took over a month for it to show up at my door, it was exactly as described. 

It was covered in a rusty dust and had a very funky protective flexible conduit attached. I removed that and washed the whole unit. I inspected the flex seal in the nose and everything looked really good. 

The next thing to do was to test the contacts - I hooked up the DVM and tested the Red/Blue pair. Everything looks fine. 

Looks like I got myself a probe.

Now all I need to do is source a waterproof conduit and the fittings to seal to the probe, mount the probe, run the conduit, mount the interface card, figure out where to add the probe signals to the machine I/O and calibrate and test it. It'll take weeks, but I'm pretty interested in getting it in.
