I pulled this up on You Tube:

Towards the end there is mention of the Mustang Ranch but very little. I doubt if he did any of his adventures with money from the ranch. He said he was raised by his grandmother and was apparently living off of the wilderness. This was an interesting video, although I could not find anything in this video about the Mustang other than his mentioning the Mustang. However, I didn't watch all of it.
