Matching Old Natural Pine Tongue and Groove Boards

Is the pine yellow pine or white pine? I would stick with the same spieces if possible. I would make some test boards and try different finishes and compare. If coloring is an issue, you might consider using aniline dyes to get the color right. It is usually hard to match just by using stains alone.

I have had good luck using amber shellac.

I agree with Sam that this is going to be a challenge to do. Another option would be to use trans tint dyes and I would put them in a shellac base since it dries quickly. I am sure that you will have to prepare a mixture of dyes since you are working with (1) aged pine which takes on a yellow to brownish cast and (2) poly which changes to an amber color as it ages.

If I were trying to do this I would go with red, yellow, orange and brown dyes adjusting the strength of the individual dyes on test pieces until getting the color matched as closely as possible.

Also I would apply a seal coat of 3/4# shellac to the pine before staining to help with the blotching.
