Query: Absolutely the B E S T book ever written on Spencers.

This is the BEST book ever written on the subject of Spencers. I have 4 Military Rifles, one of which is the model 1870, and I have always wanted to know more about the man and his weapon, and this book answered every question I ever had. Easily worth the price!!!
