Another beautiful gun you have there Ron.
One of the guns I really regret selling was a fine old Drilling I got in an SF pawn shop in 1965 for about $250. 16X16 over a 9X57R. Had the 2 9/16ths chambers opened to 2 3/4 inches. Made before WWII.
The only thing I didn't like about it was the Greener Side Safety. The button was too small to catch easily and quickly.
But, other than that, it was a great gun. Horn trigger guard and chambered for a rd. very similar to the .358 Winchester. E
