Item no. 1: single folio, 2-7/8" wide x 3-1/8" high. Item no. 2: single leaf, printe both sides, 2-7/8" high x 6" wide folded to 3" wide. Example No. 2: The box for this one has the stock number on the front panel in the same position with with the name below changed to "Tru-Point Model D Pencil Lead Pointer" and below that, "with "Quick Change" Abrasive Cups." There is no longer a separate label on the side panel. Example No. 1 obviously was issued before no. 2 which has little or no signficance other than to differentiate between the two boxes here. Knowledge of any models A to C, if they exist as such, is unknown at present and these items may not even have been made by K&E as these types of sharpeners became more or less standardized and thus a generic type of item among many suppliers. It is quite possible that it was simply customized with the cap for the K&E product line. K&E had their main office and factories in Hoboken up to December 1968.
