There was a bit of a delay while I got hold of a copy of the Hymnal; the treble edition, with tunes, which was most widely printed I think. Unfortunately, you only get full indexes in the 'Complete Music Edition', as it turns out, so it takes time to locate tunes in the book by name. More delay, and then other things intervened.

Now the thread is back, though, I'll just mention that I did compare the 'Dives and Lazarus' tunes, and 'Kingsfold' is indeed the form got in Westminster and printed by Broadwood and Fuller Maitland, not the variant that RVW himself got in Kingsfold; so his naming convention was evidently a bit more elastic than I originally thought; though still logical.
