Hi Ulf,

I don't have a service manual, I think that it does not exist since HP 
stated that it was not a field maintainable item and any attempt to 
adjust it would void the warranty. Anyway I have a schematic and a brief 
circuit description from the HP 105 manual, which uses the 00105-6013 

This oscillator was also used in the 5065A Rb standard. Its manual has a 
section devoted to this oscillator including theory of operation, 
operational checks and schematics.

The HP 5061A Cesium standard also used this oscillator and its manual 
includes schematics and a section about testing this oscillator.

I can extract the pertinent sections and schematics from the referred 
manuals if you think that it could be useful.
