Has anyone purchased this book on the Development of the Krag- Jorgensen?

I see it often on ebay. It is a 180 page soft-cover, self-published, and sells for around $51, shipped.

I wonder about its quality, value and content?

(BTW - Regarding the original posted question, "Mallory vs. Poyer?", I find my second edition of Mallory's "KRS" my most interesting and trustworthy Krag book.
I cross-check things in Mallory against Brophy's, "The Krag Rifle".
I find Poyer's book very useful, but, cross-check everything).
