[time-nuts] Manual: VARIAN R-20 Rubidium frequency standard.

[Ulf Kylenfall]

Gentlemen. 
I have salvaged a manual for a Varian R-20 Rubidium Frequency Standard. 
 
It was left when my employer borrowed such a unit when 
performing the first cross-atlantic VLBI Experiments 
some time in the late 70's. The unit must have been returned to its 
owner but they forgot to include the manual... 
 
It is in excellent shape. 
 
Are there any such units still in operation? 
Is there a need for it? The thickness of the papers 
is about 1 inch. Most pages are easy enough to scan but the 
last 1/3rd is fold-out schematics for which I have no 
appropriate way to scan. 
 
Best Regards
