I did not read this article in 1948 though I feel reasonably certain I read it in F&S. I am positive when I did read it the gun was a Lefever. It is quite possible the original version was run in a special issue at some point. I do recall F&S putting out some of these on occasion. I recall once when they ran an entire magazine of old stories with some dating back to even their first year & then others on up through the years. I believe this was put out separate from their regular subscription issues & had to be bought separately.
