84th of Foot Collar Badge 1878 to 1882

This example is homemade and is made from the Union Rose part of a Helmet Plate Centre. Remains of the stems connecting the rose to the circlet of the HPC can be clearly seen on the rear view. 

This can be dated to when the Home Service Helmet/Helmet Plate Centre came into use in 1878. It is slightly smaller than the purpose made collar badge by 2-3mm.
