flooring boards (Firth Park S5)

Old attic tongue and groove floor boards made of chipboard, 600mm x 2400mm (almost 2x8 foot) 25mm/1 inch thick. 5 full boards and 3 part boards (3/4 length give or take). Good, solid, dry and heavy and a bit dirty. You'll probably need a van to collect them due to their length. I can help carry them down to the van but can't deliver them.
Only getting rid of them because the t&g doesn't match the t&g on the boards I'm covering the rest of the attic with. Ideally all to go together.
