I went through my old daylily catalogs and found one from Wild's dated 1991. They did not have a photo of 'Many Waters' (MW) in that edition. If I remember correctly they would put photos of different cultivars in their catalogs each year so a later or perhaps earlier catalog may have a photo of MW. Perhaps you might try emailing Wilds and asking if they have a photo they could share?
In any case, here is their full description of MW in case it might be a bit more helpful.
"A beautiful, ruffled, crimped strong lavender with mauve veining, shading, self-colored raised rib. Wide yellow green throat blends 3/4 way up on rib and nearly 1/2 way on sepals, & ends in a lovely mauve edge, green heart. By evening rib is nearly cream, edging is still visible. Good substance, branching."
