I’m hoping that someone who owns a Zabala-built 28 gauge side by side will take out a Vernier caliper and give me two measurements. I need to know the length of the barrel flats, front to rear, and the diameter of the round section of one barrel, immediately in front of the barrel flats. These could be from a gun sold as Zabala Hermanos, Richland Arms, Kassnar Arms, American Arms, etc. Your help would be of great assistance to me in planning a new project.

Best of the season,
Ron Vella.
