A good friend of mine is in Afghanistan and asked me to hold on to it for him. I know very little about the rifle other than they were originally black with a checkered pattern. Unfortunately the one I have is acorn with a basket like design.
The few I seen had had stock colors from kinda light to somewhat dark in stain. All checkering and a good blued finish. Lots of good info here.-http://www.wisnersinc.com/additional_info/winchesterl_88_100.htm
