A RARE throwback to the old days of mining will be going under the hammer in North Yorkshire this spring.

The miner's dial is a brass-bound compass that colliers would once take down the pit with them to help navigate underground.

On April 3 it will be sold during a special collectors' sale by Tennants of Leyburn, when it is expected to fetch between £200 and £300.

The dial was made in the North-East, by a Newcastle company, and was used by miners from the old North Bitchburn Coal Company.

"With its connections with the region we expect this will be of great interest to collectors," said valuer Sarah White yesterday.
