Knife appears to be a 73878 3/4 shown on p. 202 of Sellens.
I would say that the knife is a Camillus made knife based on the following, first the "K" in the pattern number, I generally only see that on Camillus made knives. I assume that the "K" is underlined. The grooved bolsters are common on Camillus knives, however, I haven't really seen it very often on Winchester or Walden knives. The Keen Kutter logo should have the little ears at the top of the wedge, if they aren't there I'd be surprised. Finally, the shield shown in Sellens is the old logo shield, however, if you look at Sellen's dates they are 1921 through 1938. At the beginning of that period the knife would have been a Walden knife, at the end a Camillus. This knife is a later version in my opinion. Camillus made knives both with and without the "Simmons" on the logo.
I can't see anything about the punch that sounds any alarms.
