Serial Number 528110 was reported as inaccurate.
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!

Shouldn't change the data for this serial range,
I'll just enter the details on this serial itself.
