In my old family house in Livorno, Italy, we had a nice large rose bush of a variety we bought at Barni, Pistoia, which was sold as Kazanlik (which should coincide with Trigintipetala). I thought it was mislabeled right after its first blooming season.
It was very double, quartered with a large button, a little bit deeper pink than how Trigintipetala should be, especially in the first two days, and it had the same red linings on external petals like Leda, which were especially obvious in buds. It was literally exactly the same of Leda, but with a vivid pink base.
As all this happened back in late '80s, I had no idea about the existence of Pink Leda, until I read about it on some books. From then, I remained very convinced that our plant was actually Pink Leda, and not Kazanlik. The confusion was maybe made possible by the fact that it's a pure damascena hybrid as well, with great vigor, very healthy and floriferous, not repeating and with a very stunning fragrance. Not difficult to believe that it's used for rose attar production... maybe it's really another one of the cultivars used in Bulgary for that production, who knows.
Later, my mom bought another plant of this variety for her new home, at the same nursery... It was still the same. I actually think they're still selling it today as Kazanlik.

p29 Rose Review. Jay Williams says Leonie Bell discovered that Pink Leda preceded the 'Leda' that is white. The white 'Leda' should be 'Bordee de Rouge'. Both date from 1827, can be found on Page 115 of Desportes. Reference - Old Roser's Digest, April 2000.

This rose bush is for me one of the best old garden rose bushes. It is well shaped and the foliage is rough and healthy. It endures rain and hot sun and blooms very reliablely. And last but not least the blooms with their warm pink, folded petals are beautiful.
