I foolishly traded my copy for Sixguns, by Keith some 35 years years ago. I still have access to my bother's copy, though.

I recall much of it and re-read it now and then - about every 10 years or so.

Ned was pretty much on top of the game.

Another good book of his, is the

Major Ned H. Roberts

and

The Schuetzen Rifle

1951

I have and purchased (1988) the Revised Edition by Gerald O. Kelver 1983.
