Not much to add, but here is a real nice 67 case. I have had the best luck with fine soda blast to clean and a blend of the 2 alodines. Pics do not give the real look, to the naked eye the outside looks like the darkest area of the inside, with that slight sheen, fwiw. The lighting angle slightly washes out the gold look depending on the angle, but the dark alodine is way too dark without work/experimenting. It should also be mentioned that these items were dipped before final machining, likely at the casting plant, so perfect is about impossible.
