2 Wooden Beams (Pinehurst SG13)

2 lengths of Wood 76.5" x7" x2" + 86"x7"x2" fixed together as a shelf , used in the garden so are well weathered. They need to be detached from holding post i.e. sawn down 6 inches or cut through 1 screw which attaches the wood but has a faulty head . Please let me know when you can collect
