I'll give you my choice.
First, properly prepare the wood with finish sanding.
Now brew 5 teabags in one cup for extremely strong tea (tannic acid).
Prepare an enclosed wooden or cardboard box with plastic or glass viewing window. Wipe the stock down profusely with the strong tea.
Put commercial grade ammonia (about 28%) in an open tin (like a tuna fish tin) in the box and allow the ammonia to fume. Observe the color change and remove stock when desired color is reached. This will likely take about 4 hours. Note that this is commercial grade ammonia and not household ammonia.
Remove stock, allow to dry, and start to apply finish.
A friend took a stock so finished to the American Gunmaker's Guild and had to tell everyone how he did it as the color was so magnificent.
