I have no way of knowing whether this book is the work of the elder or junior Askins. The title page and copyright are in the name of "Charles Askins," no military rank indicated. Perhaps the original copyright of 1910 would determine which Askins is the author. I mean no disrespect by not referring to a military rank as I am not aware of the proper rank of the author or whether this book is written by the non-rank bearing Askins.
A "junior" or "senior" is not indicated in the book.

Anyway, for those of you familiar with this work, I am sure you would agree that it is helpful and is a good resource. Like I said, I am tickled with this find.
