Hi all, Roy, The 10Mhz change is not covered in a manual but comes in an Update (yellow pages). Its about 1/4 thick double sided. The copy that I have appears to be complete.

[time-nuts] The HP 105B Quartz Oscillator
Fellow time-nuts I have obtained a venerable HP 105B, and I am pleased to find it has the later, and I think superior 10811 – 60109 Oscillator. I have found the download for the manual, but this covers an earlier version with the old larger 5 MHz Oscillator. Is it possible that one of you may have a manual for this later version ? – it would be much appreciated.

Re: [time-nuts] Trimble OCXOs - 6525, ... and ...
Hi I have not seen a Trimble OCXO with an internal trimmer for frequency set. They probably do exist, but they are not common among the newer (post 2001) parts.
