Research Note: #580953: Verified as a 7-Jewel Gilt movement. This serial block was designated as Model 6 in factory records. However, no grade classification for a 7-Jewel Gilt Model 6 has been documented to date. We have classified this run as Grade 33 since it represents the most consistent grade and was known to have been produced in Model 1 and Model 3 variations. Pending further discoveries, it is logical to conclude the company may have continued the use of the Grade 33 classification for this production run.
