Actually Daryl, that cover is the 1977 Gun Digest that you may be referring to in your post.
The brass-mounted longrifle on the left was made by Monte Manderino, who at the time, was studying gunmaking under the late John Bivins. I believe Monte was either a graduate of the Colorado School of Trades or Trinidad Junior College School of Gunsmithing.
The rifle the right was made by John Bivins for my "Partner in Grime", the late Lewis Sanchez of Tampa, FL. The "Hunter's Star" is inlaid ivory & ebony. Lewis, in turn, built a rifle for John.
My rifle, built by John in 1977, is the same architecture as Lew's rifle, except mine is little more subtle in the decorative artistry. Mine was John's first build for a left-handed owner, and the Siler lock, one of the first dozen left-hand locks Bud made, was fitted & polished by Monte. His initials, "M M", grace the inside plate of the lock.
I may have the rifles reversed as I am breaking the NC Governor's ruling about being with just immediate family members for Christmas, and not at home to check myself.
