Any luck with the elusive "L" marking?

I did some digging on archived LR/WF guns images that had been on the Internet over the past few years. I came up with about 25 images of the LR/WF guns that I was able to look at the frame water table. My results...I came up with zero guns that had the "L" stamped on them.

I know there are quite a few more out there that may prove the "L" was usually stamped on gun... but I wonder how Mr. Houchins was able to say that they were usually marked with an "L. Did someone from Hunter Arms tell him that? Did he have some correspondence or document that indicated that the LR/WF were so stamped. "Never say Never"

In any case, John Houchins and "The Legend Lives" is the most fascinating and colorful collection of information for the L. C. Smith enthusiast. A must have!
