LEJ,
Sorry, the bottom one (built in 1992)was originally chomium trioxide. This was my third rifle and by the time I noticed the first two turning green, I had already stained this one with it. (don't ever use chromiun trioxide as a stock stain) I stripped the finish off as best I could and restained with fiebings leather dye. In the right light you can still see some green but it is ALOT better than it was. The middle rifle (built in 1996 or 97)was stained with fiebing leather dye. I think it was some kind of blend with dark brown, light brown and mahogany. It has faded a fair bit from when new. The top one (built 2003) stained with nitric acid (aqua fortis).
