Good clean Royal Artillery officers bronze cap badge, made by Firmin of London.
This example features twin securing blades to the rear and is the 'spinning wheel' variety, meaning that the centre wheel is on a pin bar and can rotate.
The bronzing is around 99% clean and not chipped, though there is some extremely minor loss.
