Hello before I start the cabs, I need to understand if I need to replace/add a new floor or I can restore it. I love the old T&G floor but there are huge gaps between the planks, some pieces are broken or missing (max 10"x5"), there are holes due to an insulation job underneath (cellulose is coming out the gaps as well), etc. I would love to have a modern Plywood floor or keep the one I have finding matching pieces and restore it. While I can go about the first option, I do not know where to start with the second one. I have no idea what pine it is and how to treat a new pine to look like the old one. The house was built in 1939. Here the pictures, the rough floor is the actual attic floor. The last one is the plywood floor I will install if I cannot fix the existing one. I will add the ply to the existing floor (cross direction). Thanks for helping
