I am familiar with this book as I have what is very probably a first edition. Mr. Askins, the senior, lived in Oklahoma near or in the town of Ames. Askins Jr. was born in 1907 so the author of this book had to be Askins Sr. My grandfather, John Overton Hughes, was a friend of Mr. Askins and is featured in pictures in the latter part of the book in the chapters on wing shooting.
My grandfather field tested Winchester shotguns during the early part of the 20th century as well as raising championship pointers. My father also knew both the senior and junior Askins.
The book I have is one given to my grandfather by Askins. It is rather worn but interesting to peruse
