Poyer's book does contain a wealth of information and a few errors, but the Krag bible is from Lt Col William S Brophy "The Krag Rifle". A Krag collector needs both on hand.
kraigwy, is that a 1898 rifle? I see it has the 1901 rear sight. Finish is very nice on that one. Getting hard to find unmolested Krags. I picked this 1898 up yesterday, not near as nice of metal as yours.
I sure wish I had been around for this ad.
