The chips were ordered from the Mason Co, They had offices in several states including IL, CA and MO.

We have access to the Mason records for hot stamped chips but there are very few records on inlayed Hub molds.

Mason did not actually make chips. In this case Mason ordered your chips from USPC in Cincinnati. If ordered after 1947 they would have been made in Maine at the Burt CO. We do have some Burt records.

Here is the USPC record showing the CEF were shipped to Kansas City in 1932. Where they went from there is a mystery.
