I now own this Carbine......
I made the purchase tonight !!! He is going to dig out all of his Grandfather's old "Service Papers" and Spanish American War Medals & give me copies and photos. I'll post updates as I find out more information.
Two weeks ago I didn't know a Kragfrom a hole in the ground........I still don't, but I know a hell of a lot more than when I started.
By the way........I measured the barrel as Chuck suggested and it's exactly 22", I checked the front sight and there is no silver solder of any kind, just blue on blue, and I checked under the trapdoor in the butt plate, and there is a single round hole, with three small holes drilled in the far end.
Thanks to everyone who helped me out ..........The internet and these forums really allow a sharing of knowledge that really wasn't possible in the past........and in my case sparked a new interest.
