A Silsden Civic Society member says he is baffled by the coat of arms on a miniature First World War tank.

Neil Cathey, of King Street, Silsden, a local historian said: "Silsden did not get a coat of arms until the 1950s so this really intrigues me."

But the china tank bearing a Silsden crest would have been made some time during the 1914-18 war.

Last week's Keighley News reported how it was discovered by Laurie Jones, of Durham, on a Cross Hills building site.

He had left it with friends Denis and Barbara Wayte, of Ridgway Mount, Keighley, so they could find out more about it.

Keighley historian Ian Dewhirst has revealed this and other crested china items were sold as souvenirs from the Edwardian period until the 1930s. Although most of these items were mass-produced at the time, he said the Silsden tank was the first he had ever seen and he had only ever seen two bearing the Keighley crest.

The tank made by Swan bears a reference number 658580.
