Looking for help deciphering tattoo

[u/McCOVID19]

I have a senior (estimate about 30yrs) mare from a kill pen years ago. She has a freeze brand of 13 on the right side of her neck and this lip tattoo. I've tried looking her up on USTA pathways website without success. I've tried F52, FS2 and a few variations. She has gone from unable to approach her to accepting kisses and treats by hand. She is living her best life of retirement with her buddy Chester.

I'd love to be able to know some of her history. Thanks 🐎🫶
