I have not seen the rifle in question, but have owned an original. The best repro Baker parts and, by extension, kits I have seen come from The Rifle Shoppe in Oklahoma - www.therifleshoppe.com. I have found them to be a very frustrating company to deal with, but their parts are worth the aggravation.
