Wieland:
For the 5-element "Model I" -
The numbers on the DOF scale read as "22168 81622" (with all the numbers
"squished together", except in the middle, and with no label for f/4). When
set at infinity, the feet scale reads as "10050" ("squished together"), while
the meters scale shows "30 15".
For the 6-element "Model II" -
The numbers on the DOF scale read "22 16 8 4 8 16 22" (with spaces between
the numbers, and with a label for f/4). When set at infinity, the feet scale
shows "100 40", while the meters scale shows "35 15".
