Builders' Scaffolding Planks (Cotham Ward BS6)

These planks were retrieved from our attic, where they had probably lain since the house was built in 1966. Some were too long to extract and had to be sawn in half. Now they are between 1.5 and 2 metres long. Cross section is 3.5 X 22 cm. They are to some extent caked in plaster or cement.
