Dating from sometime in the late 1860s or very early 1870s this unmarked carte de visite shows a Assistant
Instructor in Gunnery of the Royal Artillery with his wife and young son. His chevrons are those of a sergeant major
with four chevrons point downward on lower cuff surmounted by a wheeled cannon and crown but with the addition
of an additional badge on top of the chevrons consisting  bursting bomb at the lower point of the chevrons with two
crossed cannons on the chevrons themselves surmounted by another crown. This was definitely one of the more
complex rank badges worn in the British Army at the time.
