First off let me say Hans does not need defended, its good that things like this come to light through whatever method. I did not mean to sound like I was bashing Mr. Van Meer either, I was just pointing out something I already knew.

I didn't read your post as Hans bashing; although, re-reading my own I can see where you got the impression I did ---and for that I apologize. The bad, or at the least lack of clarity, is on me.
That said, I think we agree that it's great for the community at large when forgotten, obscure and/or little used techniques are brought back to the fore --- especially when they're championed by someone as respected as Hans.
I'm pretty sure there's a beat up copy of that old Sunset volume collecting dust in our public library --- seems it could be worthwhile to read through it again and see what else I failed to notice when I first looked at it I can't remember how many years ago.
Something worth noting: I probably wouldn't have been inspired to try the method without Hans endorsement (and crystal clear drawings) --- just re-reading it in Mr. Naka's book (or the Sunset edition) probably wouldn't have prompted me to get out the gouges and chisels.
