I was fortunate enough to find a link to the video of a fight between the White Crane Style Grandmaster (Chan) and Wu style Tai Chi Grandmaster (Wu) which took place in 1954. Please note that Wu was already in his sixties and Chan was around 31 at the time. According to the description in the video, which is in Chinese, both fighters had signed an agreement to relieve any liabilities to each other, even if they were killed in the battle. The result of the fight was a draw.
One comment is that I would like you to defer your judgments about the fight until at least a month later. You will understand what I mean when you are done with the video.
Here is the link:
