However, the later book In the Nick of Time states that Ken Maynard was doubled by his brother Kermit Maynard. The physical similarities between the two makes it difficult to spot the difference on screen between actor and stuntman. Maynards horse, Tarzan, had three doubles, one of which was blind. ........
