Back in the early 80s did some faux looking work on barrels
Polish the barrel bright, then take a string soaked in browning
solution, wrap the string around the barrel, let it sit for a couple
of days, then do same process with a different size string and a
different browning solution let it sit on the barrel a couple of days
Then either blue or brown the barrel
My good friend Dick Hart of the old Oregon Trail Rifle smith's was
At that time pretty handy at getting a believe able faux finish
