Research Note: Evidence supports that this run [8,489,001-8,490,000] may not have been manufactured entirely. Only one observation is known: #8489005. Elgin Master Records indicate recoiling clicks and dust rings were added to the Grade 149 starting with 8,489,001. However, the following note states 500 (7,027,000-7,028,000) from the next run of Grade 149 were returned to the plate department to be fitted for the recoiling click.
