Balsa wood (Newport East PO30)

Large quantity of balsa wood and thin plywood, 1mm & 2mm. Uplifted from a friend of mine who was into aero-modelling. Slightly damp, nearly dried out now, was kept in a leaky shed. Too many sizes to list, but the plywood alone would cost maybe £50 or more to go by eBay prices.
Has to go quickly, no room to keep it for long.
