Cole-Steel's Page-End Indicator

For two months, I have been trying to figure out the Page-End Indicator on my Cole-Steel portable typewriter. I began to explore sites written about the ABC and Cole-Steel portable typewriters (the ABC was the European name for the Cole-Steel) When I found this instruction page on Will Davis' site, I was ecstatic, and amazed at how truly simple the Page-End Indicator on the Cole-Steel truly is. (It is so simple that it is difficult.)

The German instructions for the Page-End Indicator
(originally from Davis Typewriter Works, davistypewriters.blogspot.com)

This diagram shows three sizes of paper (A4--roughly 8 1/2 x 11 inches, A5--roughly 8 1/2 x 5 1/2 inches, and A6 paper, which is smaller. These sizes correspond to the shapes on the right carriage knob of the Cole-Steel. Here are approximate instructions for using the page-end indicator:

1. Line up the arrow with the rectangle that matches the size of your paper--the long rectangle is for Letter size, the smaller size is for Statement (1/2 letter).
2. Insert paper into the carriage.
3. When the rectangle for letter appears for the third time, you are at the end of the page. Remove the paper, and repeat steps 1-3 for each additional page.
