Tom McIntyre recently posted examples of most of the high-grade Illinois approximately 12-size watches. He did not have examples of two other grades worth mentioning. Grade 435, with 17 jewels, is the plainest of the 435,437,438, and 439 family of grades. It is uncommon. Only 310 were made. Here is an example from my collection with the original unsigned 14k case, original dial and correct hands. Grade 409 seems similar to the 23 jewel Illini except that it has chaton-set jewels, 21 jewels, and at least one diamond end-stone. My example is in a 14k Knapp Illinois-signed case.
