Help Identifying a Brand

This isn’t technically a “missing horse” post, but I didn’t know where else to put it…

The horse in question is called Tori. We know almost nothing about her past, but we are fairly certain she was a PMU mare. We don’t know her breeding, but we think she is a Quarter Horse/Belgian cross (typical for PMU horses). We do know that she is 13 years old, and came from Canada.

Anyway, she has two brands (technically one brand, but printed twice) on her left shoulder. I’ll link a picture below, but it looks like a capital S (although it might be a 5) with the ^ symbol over it. Does anyone recognize this brand? I would really like to find out this horse’s history and information.

Thanks everybody!

Does anybody recognize it?
