This picture depicts overlap between letters which is an indication of kerning. The other test is to show that the individual letters are not monospaced; i.e., that the number of characters per inch varies with the type of letter. A couple of full lines at the same magnification would be helpful.
Someone actually argued that kerning can occur on typewriters if the striker is slightly bent from excessive usage and the typists types extremely fast. Apparently the Klondyke twin BC has kerning also. This is the claim to refute kerning. Anyone want to comment??
