Territorial Force Imperial Service Badge (Gilded metal example ? )

Not seen another example in gilding metal finish instead of the normal white metal.

WW1 era Territorial Force Imperial Service Badge, introduced in 1910 under Army Order 3. It was worn on the right breast by Territorial Force officers and men who had volunteered under the Imperial Service Obligation to serve overseas in a national emergency, rather than being restricted to home defence. It was a horizontal bar surmounted by a royal crown, with the raised inscription “IMPERIAL SERVICE,” 10mm by 43mm. It ceased to exist when the Territorial Force became the Territorial Army in 1921, and by 1913 only 7% of the Territorial Force had signed the obligation.
