"Kf" or "K" in place of Barrel Steel on bbl flat

[Gary Laudermilch]

118298 - 1903 - Marked appropriately with a circled T and some distance away to the right of the barrel type stamp is what appears to be a lone "C". No k/kf

156428 - 1910 - Marked appropriately with a circled V. On the opposite side there is a circled JG. No k/kf

I'll check a few more later, but 95618 has the kf. It's a 12 gauge VH.
