Attractive Phal NOID

[Hedge]

In January I inherited a collection of 6 Phals from a friend who had sadly died. The state of the roots meant most had lost the will to live, but I repotted them, and now three are flowering. I think this one is particularly sweet, it is a small flowered variety, and the way the yellow edges the lip I find particularly nice. Any clues as to its possible name would be appreciated
