i'm sorry to say that i don't know this form your asking about. i've only been into learning martial arts for around a year and a half. when i started i wanted to learn wing chun. right now i only know the first form siu lim tao. i also learned that wing chun alone is not the best for self defence. so i now mix siu lim tao with jkd and boxing. anyways the only forms i know exist in wing chun is siu lim tao, tsum kui, and biu jee. also luk tim boon kwun/six and a half pole and baat jam dao/eight cutting knives. and muk yan jong/wooden dummy. sorry i could not be of any help but if you do find anything out about the form your seeking, then post it. i might would also look in to this form to see what it is. thank you
