New Member Barrel Marking Question

[Researcher]

The 1 on the bottom of the barrel lug is the frame size meaning the center-to-center firing pin spacing is 1 1/16. The little K and whatever the other mark is on the lug are unknown. My 2-frame VH-Grade, 106580, has a very tiny 6 next to the 2 on the barrel lug.

The WK in the oval is the Walter King inspection mark. Not on my gun.

The Kf has had a couple of explanations over the years -- 1. that it is the Charles King finished mark; 2. and much more likely, it is the steel mark as it is found in the steel mark location on many early Vulcan Steel barrels. The Kf is in the same location on my gun.

The V on the watertable above the serial number is the grade of the gun.
