Thanks Kent ... did you note if it was a 17 or 21 jewel?
The Illinois Central is quite common in size 12 grades, I can only give estimates from the info I have.
17 jewels Grade 127…estimate 300 bright lined movement.
21 jewels Grade 274…estimate 4,500 rayed pattern
21 jewels Grade 279 ...estimate 1,100 rayed pattern, this includes 700 from Grade 121
17 jewels Grade 404…estimate 4,350 sunburst with tutoned wavy lined center.
17 jewels Grade 405…estimate 6,100 sunburst with tutoned wavy lined center
Do we have similar statistics for the 16s Illinois Centrals?
