Formation sign of the Northumbrian County Division. St Oswald's shield on a blue field. Traced from IWM jpg scaled to 500% with minor rotation/skew applied. The design was also used as a uniform patch by Northumbrian Home Guard units after the county division was disbanded. Note: this is the war time six bar version, the post war version has eight bars.
