Oak parquet floor blocks (Chelston TQ2)

Some oak parquet floor blocks available. A couple of the rooms in our place were already laid out in this when we moved here, and we found a few hundred of these sitting in the garage as well. I believe the previous owner laid the floor himself, so I guess these were spare. I haven't inspected them, the visible ones are a mixed bag but mostly seem good. Each tile is 23 x 7 cm / 9 x 2.75 inches. At a rough guess I'd say there are between 300 and 400 blocks here.
