I am sorry but I do not see Paph. stonei. I do not see stonei’s strongly jutting pouch. Petals of stonei in my mind do not twist as much. Where is the little white patch at the central base of the dorsal that so often appears in stonei hybrids? Stonei has a much more cupped or hooded dorsal. It can be annoying.
But it seems to have the appearance of a St. Swithin or a philippinense hybrid. Just my 2 cents worth.
Come to think of it, I seem to recall a more ‘squat’ dorsal, broader yet shorter. These seem to be a little narrower and much taller.
Edited to add, I see a St. Swithin petal stance, they are at a pleasing downward angle. On line, and in the Orchids Plus and Orchid Wiz programs, there are numerous examples of lighter or paler colored St. Swithins. Stonei has a petal stance akin to a “bow legged cowboy” who spends too much time on a horse.
