Sorry, I do not have that manual on hand.
However, if anyone's interested, I have manuals for the following HP
103AR quartz oscillator
105A/B quartz oscillator
113BR mechanical clock (a rare bird and a fascinating manual)
and the Efratom FRK rubidium source.
The above manuals were all salvaged by an astute engineer here at
Steward Observatory as NRAO's local office is moving itself from
Tucson to Charlottesville VA.
I'd be happy to scan these as time permits to get them on the Web,
since they do not appear to be currently viable products for Agilent
and the manuals aren't available as scans anywhere that I know of. I'd
want to talk to the Agilent fellow first to see what he thinks.
Curiously, Agilent's obsolete PDF index lists the 105B as sold to
Symmetricom, although they don't have it on their website. Presumably
they have killed it as a product since it competes directly with the
1050A they sell already.
