.357 PCP Custom Pistol-need help

I took this in on trade the other day because it was very unusual and looked like a very good build. .357 cal pistol. I'm trying to find the custom smith who built this or if anyone knows something about it.I believe he was in Utah, but can't really confirm this. It is not that old. #001 built in 2018. Any info would be appreciated. Photo doesn't show stock, as I am in the process of refinishing the glass stock. Thanks
