I have added a reference which says "Laurel Hill" closely resembles 'Mrs. B. R. Cant'. There is a foundling in Australia which is also said to resemble 'Mrs. B. R. Cant' called "Sylvia Hannah's Dark Pink Tea" and there are photos in that file.
Thanks for that tip Virginia. I'll investigate 'Marie Ducher' and add refs as soon as I can (fingers are nearly down to the bone here) but on a quick glance, it certainly was widespread in Australia. Later edit - it seems there was possible confusion with the white/cream 'Ducher'. Somehow, "Sylvia Hannah's Dark Pink Tea" doesn't strike me as a Dijon tea but I could be wrong. I am currently leaving all hips on my "SHDPT" to compare with 'Mrs. B. R. Cant'.
