Sadly, WO100/77 is only partially available on line, so the chances are you will not have missed it.
The best thing to do, is obtain a reader ticket, order the volume and present yourself in the reading room upon the particular day in question.

I downloaded WO100/77 from the National Archives sometime ago and have been through it a couple of times. Can you help by pointing me to the right page, please, as I haven't been able to find the reference to Pepys shown in your photo (and more importantly for me a similar entry for my grandfather, James Joseph Smith!). It's such a big document, that I must have missed it, if you're sure this comes from WO100/77.
Much appreciate any wisdom you can impart!
