Reclaimed, vintage, 3 1/4" reclaimed Douglas fir, tongue & groove flooring that came to us from a local deconstruction outfit. All this material has some paint on the top surface e. It has not been tested for lead based paint, but you can bring test strips down to check. We've tried to make sure there's enough tongue & groove to be able to reuse. Thickness is still fairly good (~3/4"). If it seemed to thin on top, we culled it. Sold by the square foot in bundles of four. Some flooring is vertical grain, but there is some flat grain in the mix. I noted very few knots on the bottom sides of just a few of the 1000+ boards I wrapped up today. Most lengths are 4'-12', but there are a few bundles longer and a few shorter.
