Yup, classic Camillus 5754!
Phil, I'm afraid my knowledge of the English language is not enough, but I hope that you will understand me.
I noticed that the models #CCC-1 and NKCA 1988 have a rivet (fastening scales, liners and springs) are shifted closer to the lanyard hole. A model #719Y, #10 and #CSS have a this rivet in center of handle. What is the reason to the change in this pattern?
