Check out Ho Lap Tin's "The Shooting Star Boxing of Hung Pugilism".

Ho Lap Tin was a direct disciple of Tang Fung, who in turn studied directly under Wong Fei Hung.

The set presented in the book isn't a Hung Ga set per se, but Ho does depict his entire set (which he made up himself).

More interestingly, Ho has presented applications to all of the moves. All of them are geared toward defending against strikers.
