Paul,
Maybe you should check out more on the history of WCK. Dai Fa Min Kam was teacher of Fung Siu Ching who taught Yuen Kay Shan and others. He basically taught Weng Chun - the Shaolin based art with some cross pollination with Wing Chun. Weng Chun has sets Sam Bai Futm 6.5 pole, etc.
"Snake and Crane" is probably made up writer to sound myusterious. Don't take it so literally.
WCK's alleged Snake and Crane is possibly descended from Fujian White Crane, and Emei 12 Zhuang/Emei snake style...but most people's idea is Shaw Brothers kung fu theatre.
