Today's wheel is a big one: 9 x 11. It's a rope price calculator produced by Columbian Rope Company of Auburn, New York -- The Cordage City! It's in moderately good shape and pretty self-explanatory in its operation.
I actually did a bit of research on this one. The company was founded by Colonel Edwin Dickinson Metcalf, who was born in 1848. A memorial in the form of a history of the company ("The Monument") was published in 1948, which is the date of the copyright on this wheel. The company was founded in 1903. I don't know the circumstances, but the it merged out ninety years later. I guess they had a good run.
Sadly, Auburn's Wikipedia entry makes no mention at all of it being "The Cordage City" and Col. Metcalf doesn't appear on the roster of notable Auburn citizens. But Williard Bundy is there! He was the inventor of the time clock.
