Prior to 1881 and the implementation of the Cardwell reforms and with it the merging of the 65th with the 84th, regimental numbers were used on the newly introduced helmet plate.
In the case of the 84th of Foot, the helmet plate had a silver rose in the centre with a silver 84 at the base of the Garter. After 1881 and the disappearance of regimental numbers and the introduction of territorial regimental titles, the number on the helmet plate was replaced with a silver universal scroll with the words ‘The York and Lancaster Regiment’.
The helmet plate is made of gilt metal and is an 8 pointed star with a laurel wreath and Garter surmounted by a Queen Victoria Crown that displaces the top point of the star. The Garter has the motto ‘Honi soit qui mal y pense’. In the middle of the Garter is the Union Rose, in silver with a gilt centre, on a black velvet background.
Fixed to the bottom of the wreath is a number 84 in silver.
Being in existence for only 3 years, helmet plates to the 84th of Foot are very rare.
