Serial Number 528110 was reported as inaccurate.

Note: Is a grade 337 within the 345 serial number range.
This appears to be correct, and grade 337 is a
weird one where a single unit will show up amongst
other grade serial ranges. I previously submitted
"inaccurate" and said I would change the grade in
the movement details but discovered I cannot
change the grade, myself. Are you able to modify
the grade listing to 337 for this one serial
number? Thanks!

Serial Number 528110 was reported as inaccurate.

Note: One-off serial weirdo, grade 337 South Bend.
Shouldn't change the data for this serial range,
I'll just enter the details on this serial itself.
