Leybold-Heraeus Thermovac TM202 thermocouple vacuum gauge controller

Not sure if this goes here, but strictly speaking it is about test gear.

Hi! Getting into high vacuum stuff, and i've got a cheap offer for a 80's (i think?)  Leybold-Heraeus Thermovac TM202 - without the gauge head.

Now, it has a non-standard tube socket as probe connector with two fat and 4 slim pins, and the probes look a bit non-standard: https://www.ebay.ca/itm/LEYBOLD-THERMOCOUPLE-VACUUM-GAUGE-89672B1/263415925632?hash=item3d54d00b80:g:dhgAAOSw4A5Y03EZ

those thermocouple gauges are pretty simple to drive, but considering how bulbous the detector is, I fear most of the magic might be in there. Is the TM202 then worth picking up, to see if I can modify it for std. thermocouple gauges?  Does anyone KNOW this piece of gear?

Thanks in advance!
