Research Note: Original factory records suggest 2001101-2001400 were produced as 19-Jewel "Bunn" grade movements. However, multiple 21-Jewel Bunn Special movements have been observed early in this run. As a result, the database has been adjusted to reflect this production. [This run has been extended to account for the Bunn Special movements observed in the following "Bunn" run.]
