Brain teasing exercise. I think, I narrow down my search to 2 possibilities:
In some datasheets, NXP says they use marking *XX (sometimes %XX), where * (or %) ether W or T or P, depends on a manufacturing plant, W - China, T - Malaysia, P - Hong Kong
WMP= W(china) + MP(BFG520).
Looking at datasheet, I 'd say it's Chinasian tween-clone of the same NXP transistor.
Pictures is exact, don't need to make a photo.
Thanks to everyone.
