HP 2801a Quartz Thermometer Manual/Schematic needed

[Lamima]

Hello,

i got a very old (some q-control stamps are showing April 1964) quartz thermometer but without any papers belonging to it.
Unfortunately the needed probes are also missing...
I planned to make a "replacement" probe but i will need a schematic of the thermometer itself to understand how the input signals should look like.
Does someone have the manual/schematic?

Regards
Marco
