Research Note: Rockford serial lists designate this run as Grade 83. However, #405531 has been verified as marked "17 J" and "Adjusted," inconsistent with other standard Grade 83 movements and is more consistent with the Grade 82 designation. Rockford offered the Grade 83 with an optional factory adjustment, described as the Grade "83x" in original advertisements.
