This 1940's era redwood picnic table set was handed down to us and originally belonged to my husband's grandparents. It is not treated or stained. We need to replace the legs and braces because some pesky squirrels have been sharpening their little teeth on them. I want to use as close to original lumber as I can get but do not know where I can purchase it, or if it is even available anywhere. The separate benches and table top have been made from 2x's with 4 and 6 inch width boards and the braces and legs are 2x2 and 2x3. All of the boards are of the dimensions used in the 1940's, which by today's lumber dimension standards are probably not the same. Nor do I want treated or stained lumber. And I certainly do not want to use the set for kindling in the fireplace. Any ideas?
