Johnny; at one time I had a pint of G.I. stock stain from Rock Island. Over the years I've used it up, and only have a little left. I got it from a guy who had bought it by the gallon at Rock Island, I guess at an auction. I've never seen another stain just like it. I know there have been many attempts to reproduce it, but surely the formula is no secret - seems like it would be available in the documents used to procure it. If you have the right stain, you don't mind washing or steaming a stock.
