I bought Sherwin as a grade horse but after speaking to the former owner, I've come away with the info that there's a registered name: "Back in Time."
Back to The Future came out in 1985...28 years ago. Back to the Future 2 and 3 came out in 1989 and 1990...23-24 years ago. Everyone who's checked him out has put his age at 24-28 based on his teeth and general appearance.
I don't hold out much hope I will ever get copies of the paperwork so was hoping there's someway to look this up online?
I was told he's a quarterhorse/paint cross...
