This one is a little confusing to me given the supposed change in box size in '67. This one appears to be from '68 to '70 (3rd Ver./Var. 7) and according to the paperwork with it was purchased in '69 and came in the 1 1/4" tall box. The rocker rivet is brass and appears to me to be headed, but everything else fits. The knife has had some "customizing" done to it, but all the features are visible.
