Like many regiments that could trace their lineage back to those units that had fought Napoleon in Egypt, the Lincolnshire regiment adopted a cap badge in the form of a Sphinx. In the case of the Lincolnshire Regiment this was a direct descendent of the 10th (Lincolnshire) Regiment of Foot which had gone to Egypt in 1800. The Lincolnshire Regiment was formed from this unit in 1881 and in 1898 adopted the aforementioned sphinx as its badge in white metal with a gilding metal scroll beneath with the regiment’s name on it:

The badge was to be used by all the battalions of the regiment. By World War I, the First and Second Battalions were regular units, whilst the Third was a reserve battalion and the Fourth and Fifth Territorial Force battalions. All were badged the same. This particular cap badge has a brass slider on the rear to allow it to be worn on a cap:

It can clearly be seen that the badge is made up of three separate components, all soldered together. This cap badge remained unchanged until 1946 when the regiment was granted ‘Royal’ status and renamed the Royal Lincolnshire Regiment, with a consequent update to the design of the cap badge to reflect the new regimental name.
