A superb example of a cap badge worn by an enlisted man, (i.e. a private or non commissioned officer) who served in the “Leinster Regiment”.
The reverse of this badge has oval shaped sweat holes (used in the fixing process of bi metal badges). The oval shape of the sweat holes suggest that the badge is quite an early example and I’d place it circa 1900, being late Victorian Boer War era or early Edwardian. A great example and 100% original.
