Hammerback: Just came across your post. My names Buck Parker and I acquired this rifle from John right around 1988. It tickled me to see you picked this up from a gunshop in Cheyenne as I sold it through Cabelas gun library. Do you still have this rifle? In my opinion I thought the metal work John Maples did was superior to the original. The rifle originally was just the 9x56 chambering and had the Jaeger sidemount. When John built the 7x57 he put a Jaeger mount on it to match original. I talk to John occasionaly and will send him a copy of this in a email.
It was good to see this fine rifle here.
