Mario, not necessarily. I did some looking around earlier today and saw some similar designs but could not find one with three cannons. I think the crown is Queen Victoria which puts it before 1901. I also was focusing mainly on horse artillery batteries which I think it comes from. the one site that I thought would be good, I had a lot of problems with and all pics were red 'X' out. The site was diggerhistory. I cannot find a British site that has images of all the crest types. I have had much better luck researching US military emblems.
The other thing I found odd was all three cannons face right. In almost all images with cannons from British units, the cannons face left (gunners badges face right) or are 2 crossed cannon barrels. I have no idea what that significance is.
