Glad you decided to stop, P39 kit is pretty rare stuff and is only now being appreciated for what it is. While you may prefer the original color sometimes we have to live with what we have. As I said above, some units were required to blacken their kit and once leather is blackened it is blackened forever, nothing can remove it. And please remember, whenever possible leave the leather as is but if something needs to be added to replace lost oils, a light coating of PURE neatsfoot oil is far better than Pecards.
