Andre'; I will be happy to brown your barrel for you - call me - 605- 673-4072, or e-mail hjt65@hotmail.com. I am all set up for browning solid steel barrels - Damascus is another matter. I can do a "light" semi transparent brown all the way to a heavy deep brown which will not wear off of the barrel corners for a very long time. Hugh Toenjes P. S. Yes it wil be a professional job!
