Paul,
Marc has put Rees on-line. I don't know/remember if Rees mentions anything like this.
I haven't put anything online in that category and I may never do so but I am nearly three-quarter finished scanning in and recognizing Golding's Volume VI. Eventually it and (hopefully) several others will be available for download in PDF format...that's the plan at any rate.
But to your question...Golding is a compilation of essays/treatisae(?) from various authors. I think several mention cutting the feather in slightly more under the waist. Very certainly Rollinson in Volume VI does--I just finished that section and in the process more or less read it...at least enough to get a sense of it. I have been cutting the feather, behind the joint, slightly deeper even with "three-quarter" welted boots for a long time, though, so I am sure I've run across the idea previously...maybe even in other sources. I like the idea as well as the end result, myownself.
I've never run across the long lateral welt approach in the literature.It may be there, I just don't remember it. But as mentioned, I've seen it on top shelf semi-bespoke shoes. I'm sure that your usage of it where the foot demands it, is perfectly appropriate...heck, it's all mostly what you want to see, anyway, isn't it? Personally, I've never used it on anything higher than seven-eighths, but that's no sign. Years ago I read the book "A Lifetime With Boots" by Sam Luchesse (or 'as told to' Tad Mizwa). He makes a case for pegging through the shank being the more stable technique. Western boots are traditionally pegged through the shank...although if you go back far enough (1880/90's) you might make a case that they were more often fully pegged. But the point is that it's "tradition" that guides me in that particular respect. "Ropers" (7/8" ) don't have that tradition so firmly associated with them and quite to the contrary, in fact. Ropers, as we know and think of them, are most usually associated with full welts. So pegging the medial shank and welting the lateral seems a happy marriage.
Just some thoughts...hope that helps
