Serial Number 4066292 was reported as inaccurate.

Note: Following engraved on movement: "Double Roller" on
main plate, "17 Jewels" on 4th wheel bridge,
"CAPITOL, Illinois Watch Co. Springfield" on 3rd
and center wheel bridge and "Adjusted on Crown
Wheel Bridge. Roy & Bills' book identifies this
as (16S-17J-ON7P-A-"305")(ea 466). So this is a
Grade 305, Model 7. Mfg 1924. Dial says
"ILLINOIS", double sunk, Hour numbers printed
inside track, with Red numerals at each 5 min. (5,
10, 15... etc)

Serial Number 4066047 was reported as inaccurate.

Note: The movement I am looking at has adjusted
prominately by the name. Iam told when adj. is all
it says it means 3 positions. Also the grade
appears on the bridge as "forum". However I can
find no info on this grade.
