Oh, sorry! Wish I could help you :) Hope you find it, and I will keep an eye out for you!
I posted a picture of it on my feed. It didn't look like I could add it to this question
Unfortunately, my trainer, who originally purchased this bit from Jay, thinks that he retired and may have passed on. I checked out eBay and there are a few of his bits being sold, but not the one my friend is looking for. I'm wondering if there are either places that sell his bits or someone who can either recreate this bit (or design a new one to fit my friend's horse).
Maybe try to contact Jay himself and see what he could do?
