Finally got around to putting a stain on the stock of my .54 cal. Lancaster flintlock. I used a traditional method with Aqua Fortis (nitric acid) wiped on and then "blushed" to a dark color with a heat gun. Traditional method would have used a red hot iron bar to pass over the stock to activate the stain. Here are before and after pics. The "after pics" have water on the stock to give an idea of what the final product will be like after a finish is applied. I plan to use multiple coats of Tung Oil as a finish. Comments and criticisms are welcomed...............................DanielAttachment 38199Attachment 38200Attachment 38201Attachment 38202Attachment 38203
