Not that I can see, no.
The lowest he identifies is one he calls the col of Tayvallich which is twelve metres above sea level. The Jura ferry sails from it's foot.
Great to see pictures of these places. The author spends much of his discourse on the border cols talking about the wind. "One of the easiest [days I spent on a bike] was spent riding through the Scottish Borders towards Edinburgh with the broad hand of a southerly gale on my back. Now and then, a south-bound cyclist would pass, as though in a different dimension, grimacing like a soul in torment under the curse of a heaven-sent wind."
Two-thirds of the book is a lIst (or catalogue) with latitudes, longitudes and national grid references. I think it would be a bit unfair on the author to post pics of these up but from what you say about your munro days I think the book would be right up your pass so to speak.
Here's a cheeky map of bottom swire etc though...
